+
+Creative Commons public licenses provide a standard set of terms and

+International Public License
+
+By exercising the Licensed Rights (defined below), You accept and agree
+to be bound by the terms and conditions of this Creative Commons
+Attribution-NonCommercial-NoDerivatives 4.0 International Public
+License ("Public License"). To the extent this Public License may be
+interpreted as a contract, You are granted the Licensed Rights in
+consideration of Your acceptance of these terms and conditions, and the
+Licensor grants You such rights in consideration of benefits the
+Licensor receives from making the Licensed Material available under
+these terms and conditions.
+
+
+Section 1 -- Definitions.
+
+  a. Adapted Material means material subject to Copyright and Similar
+     Rights that is derived from or based upon the Licensed Material
+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed
+     Material is a musical work, performance, or sound recording,
+     Adapted Material is always produced where the Licensed Material is
+     synched in timed relation with a moving image.
+
+  b. Copyright and Similar Rights means copyright and/or similar rights
+     closely related to copyright including, without limitation,
+     performance, broadcast, sound recording, and Sui Generis Database
+     Rights, without regard to how the rights are labeled or
+     categorized. For purposes of this Public License, the rights
+     specified in Section 2(b)(1)-(2) are not Copyright and Similar
+     Rights.
+
+  c. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws
+     fulfilling obligations under Article 11 of the WIPO Copyright
+     Treaty adopted on December 20, 1996, and/or similar international
+     agreements.
+
+  d. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.
+
+  e. Licensed Material means the artistic or literary work, database,
+     or other material to which the Licensor applied this Public
+     License.
+
+  f. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  g. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  h. NonCommercial means not primarily intended for or directed towards
+     commercial advantage or monetary compensation. For purposes of
+     this Public License, the exchange of the Licensed Material for
+     other material subject to Copyright and Similar Rights by digital
+     file-sharing or similar means is NonCommercial provided there is
+     no payment of monetary compensation in connection with the
+     exchange.
+
+  i. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such
+     as reproduction, public display, public performance, distribution,
+     dissemination, communication, or importation, and to make material
+     available to the public including in ways that members of the
+     public may access the material from a place and at a time
+     individually chosen by them.
+
+  j. Sui Generis Database Rights means rights other than copyright
+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part, for NonCommercial purposes only; and
+
+            b. produce and reproduce, but not Share, Adapted Material
+               for NonCommercial purposes only.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties, including when
+          the Licensed Material is used other than for NonCommercial
+          purposes.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material, You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+          For the avoidance of doubt, You do not have permission under
+          this Public License to Share Adapted Material.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database for NonCommercial purposes
+     only and provided You do not Share Adapted Material;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+

+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. Additional offer from the Licensor -- Adapted Material.
+               Every recipient of Adapted Material from You
+               automatically receives an offer from the Licensor to
+               exercise the Licensed Rights in the Adapted Material
+               under the conditions of the Adapter's License You apply.
+
+            c. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+  b. ShareAlike.
+
+     In addition to the conditions in Section 3(a), if You Share
+     Adapted Material You produce, the following conditions also apply.
+
+       1. The Adapter's License You apply must be a Creative Commons
+          license with the same License Elements, this version or
+          later, or a BY-SA Compatible License.
+
+       2. You must include the text of, or the URI or hyperlink to, the
+          Adapter's License You apply. You may satisfy this condition
+          in any reasonable manner based on the medium, means, and
+          context in which You Share Adapted Material.
+
+       3. You may not offer or impose any additional or different terms
+          or conditions on, or apply any Effective Technological
+          Measures to, Adapted Material that restrict exercise of the
+          rights granted under the Adapter's License You apply.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material,
+     including for purposes of Section 3(b); and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

 ## About Pleroma
 
 Pleroma is a microblogging server software that can federate (= exchange messages with) other servers that support the same federation standards (OStatus and ActivityPub). What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Pleroma will federate with all servers that implement either OStatus or ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.
 
 Pleroma is written in Elixir, high-performance and can run on small devices like a Raspberry Pi.
 
-For clients it supports both the [GNU Social API with Qvitter extensions](https://twitter-api.readthedocs.io/en/latest/index.html) and the [Mastodon client API](https://github.com/tootsuite/documentation/blob/master/Using-the-API/API.md).

 * Run `mix deps.get` to install elixir dependencies.
 * Run `mix pleroma.instance gen`. This will ask you questions about your instance and generate a configuration file in `config/generated_config.exs`. Check that and copy it to either `config/dev.secret.exs` or `config/prod.secret.exs`. It will also create a `config/setup_db.psql`, which you should run as the PostgreSQL superuser (i.e., `sudo -u postgres psql -f config/setup_db.psql`). It will create the database, user, and password you gave `mix pleroma.gen.instance` earlier, as well as set up the necessary extensions in the database. PostgreSQL superuser privileges are only needed for this step.
-* For these next steps, the default will be to run pleroma using the dev configuration file, `config/dev.secret.exs`. To run them using the prod config file, prefix each command at the shell with `MIX_ENV=prod`. For example: `MIX_ENV=prod mix phx.server`. Documentation for the config can be found at [`docs/config.md`](docs/config.md) in the repository, or at the "Configuration" page on <https://docs.pleroma.social>

 * Run `mix ecto.migrate` to run the database migrations. You will have to do this again after certain updates.
 * You can check if your instance is configured correctly by running it with `mix phx.server` and checking the instance info endpoint at `/api/v1/instance`. If it shows your uri, name and email correctly, you are configured correctly. If it shows something like `localhost:4000`, your configuration is probably wrong, unless you are running a local development setup.
 * The common and convenient way for adding HTTPS is by using Nginx as a reverse proxy. You can look at example Nginx configuration in `installation/pleroma.nginx`. If you need TLS/SSL certificates for HTTPS, you can look get some for free with letsencrypt: <https://letsencrypt.org/>. The simplest way to obtain and install a certificate is to use [Certbot.](https://certbot.eff.org) Depending on your specific setup, certbot may be able to get a certificate and configure your web server automatically.

+OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.).
+Implementation is based on Ueberauth; see the list of [available strategies](https://github.com/ueberauth/ueberauth/wiki/List-of-Strategies).
+
+Note: each strategy is shipped as a separate dependency; in order to get the strategies, run `OAUTH_CONSUMER_STRATEGIES="..." mix deps.get`,
+e.g. `OAUTH_CONSUMER_STRATEGIES="twitter facebook google microsoft" mix deps.get`.
+The server should also be started with `OAUTH_CONSUMER_STRATEGIES="..." mix phx.server` in case you enable any strategies.
+
+Note: each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
+
+Note: make sure that `"SameSite=Lax"` is set in `extra_cookie_attrs` when you have this feature enabled. OAuth consumer mode will not work with `"SameSite=Strict"`
+
+* For Twitter, [register an app](https://developer.twitter.com/en/apps), configure callback URL to https://<your_host>/oauth/twitter/callback

+* For Facebook, [register an app](https://developers.facebook.com/apps), configure callback URL to https://<your_host>/oauth/facebook/callback, enable Facebook Login service at https://developers.facebook.com/apps/<app_id>/fb-login/settings/

 # Custom Emoji
 
+Before you add your own custom emoji, check if they are available in an existing pack.
+See `Mix.Tasks.Pleroma.Emoji` for information about emoji packs.
+
 To add custom emoji:
-* Add the image file(s) to `priv/static/emoji/custom`
+* Create the `STATIC-DIR/emoji/` directory if it doesn't exist
-* In case of conflicts: add the desired shortcode with the path to `config/custom_emoji.txt`, comma-separated and one per line
+  (`STATIC-DIR` is configurable, `instance/static/` by default)
-* Force recompilation (``mix clean && mix compile``)
+* Create a directory with whatever name you want (custom is a good name to show the purpose of it).
+  This will create a local emoji pack.
+* Put your `.png` emoji files in that directory. In case of conflicts, you can create an `emoji.txt`
+  file in that directory and specify a custom shortcode using the following format:
+  `shortcode, file-path, tag1, tag2, etc`. One emoji per line. Note that if you do so,
+  you'll have to list all other emojis in the pack too.
+* Either restart pleroma or connect to the iex session pleroma's running and
+  run `Pleroma.Emoji.reload/0` in it.
 
 Example:
 
-image files (in `/priv/static/emoji/custom`): `happy.png` and `sad.png`
+image files (in `instance/static/emoji/custom`): `happy.png` and `sad.png`
 
-content of `config/custom_emoji.txt`:
+content of `emoji.txt`:
 ```
-happy, /emoji/custom/happy.png
+happy, /emoji/custom/happy.png, Tag1,Tag2
-sad, /emoji/custom/sad.png
+sad, /emoji/custom/sad.png, Tag1
+foo, /emoji/custom/foo.png
 ```
 
 The files should be PNG (APNG is okay with `.png` for `image/png` Content-type) and under 50kb for compatibility with mastodon.
+
+Default file extentions and locations for emojis are set in `config.exs`. To use different locations or file-extentions, add the `shortcode_globs` to your secrets file (`prod.secret.exs` or `dev.secret.exs`) and edit it. Note that not all fediverse-software will show emojis with other file extentions:
+```elixir
+config :pleroma, :emoji, shortcode_globs: ["/emoji/custom/**/*.png", "/emoji/custom/**/*.gif"]
+```
+
+## Emoji tags (groups)
+
+Default tags are set in `config.exs`. To set your own tags, copy the structure to your secrets file (`prod.secret.exs` or `dev.secret.exs`) and edit it.
+```elixir
+config :pleroma, :emoji,
+  shortcode_globs: ["/emoji/custom/**/*.png"],
+  groups: [
+    Finmoji: "/finmoji/128px/*-128.png",
+    Custom: ["/emoji/*.png", "/emoji/custom/*.png"]
+  ]
+```
+
+Order of the `groups` matters, so to override default tags just put your group on top of the list. E.g:
+```elixir
+config :pleroma, :emoji,
+  shortcode_globs: ["/emoji/custom/**/*.png"],
+  groups: [
+    "Finmoji special": "/finmoji/128px/a_trusted_friend-128.png", # special file
+    "Cirno": "/emoji/custom/cirno*.png", # png files in /emoji/custom/ which start with `cirno`
+    "Special group": "/emoji/custom/special_folder/*.png", # png files in /emoji/custom/special_folder/
+    "Another group": "/emoji/custom/special_folder/*/.png", # png files in /emoji/custom/special_folder/ subfolders
+    Finmoji: "/finmoji/128px/*-128.png",
+    Custom: ["/emoji/*.png", "/emoji/custom/*.png"]
+  ]
+```
+
+Priority of tags assigns in emoji.txt and custom.txt:
+
+`tag in file > special group setting in config.exs > default setting in config.exs`
+
+Priority for globs:
+
+`special group setting in config.exs > default setting in config.exs`

+# Installing on Gentoo GNU/Linux
+## Installation
+
+This guide will assume that you have administrative rights, either as root or a user with [sudo permissions](https://wiki.gentoo.org/wiki/Sudo). Lines that begin with `#` indicate that they should be run as the superuser. Lines using `$` should be run as the indicated user, e.g. `pleroma$` should be run as the `pleroma` user.
+
+### Configuring your hostname (optional)
+
+If you would like your prompt to permanently include your host/domain, change `/etc/conf.d/hostname` to your hostname. You can reboot or use the `hostname` command to make immediate changes.
+
+### Your make.conf, package.use, and USE flags
+
+The only specific USE flag you should need is the `uuid` flag for `dev-db/postgresql`. Add the following line to any new file in `/etc/portage/package.use`. If you would like a suggested name for the file, either `postgresql` or `pleroma` would do fine, depending on how you like to arrange your package.use flags.
+
+```text
+dev-db/postgresql uuid
+```
+
+You could opt to add `USE="uuid"` to `/etc/portage/make.conf` if you'd rather set this as a global USE flags, but this flags does unrelated things in other packages, so keep that in mind if you elect to do so.
+
+Double check your compiler flags in `/etc/portage/make.conf`. If you require any special compilation flags or would like to set up remote builds, now is the time to do so. Be sure that your CFLAGS and MAKEOPTS make sense for the platform you are using. It is not recommended to use above `-O2` or risky optimization flags for a production server.
+
+### Installing a cron daemon
+
+Gentoo quite pointedly does not come with a cron daemon installed, and as such it is recommended you install one to automate certbot renewals and to allow other system administration tasks to be run automatically. Gentoo has [a whole wide world of cron options](https://wiki.gentoo.org/wiki/Cron) but if you just want A Cron That Works, `emerge --ask virtual/cron` will install the default cron implementation (probably cronie) which will work just fine. For the purpouses of this guide, we will be doing just that.
+
+### Required ebuilds
+
+* `dev-db/postgresql`
+* `dev-lang/elixir`
+* `dev-vcs/git`
+
+#### Optional ebuilds used in this guide
+
+* `www-servers/nginx` (preferred, example configs for other reverse proxies can be found in the repo)
+* `app-crypt/certbot` (or any other ACME client for Let’s Encrypt certificates)
+* `app-crypt/certbot-nginx` (nginx certbot plugin that allows use of the all-powerful `--nginx` flag on certbot)
+
+### Prepare the system
+
+* First ensure that you have the latest copy of the portage ebuilds if you have not synced them yet:
+
+```shell
+ # emaint sync -a
+```
+
+* Emerge all required the required and suggested software in one go:
+
+```shell
+ # emerge --ask dev-db/postgresql dev-lang/elixir dev-vcs/git www-servers/nginx app-crypt/certbot app-crypt/certbot-nginx
+```
+
+If you would not like to install the optional packages, remove them from this line. 
+
+If you're running this from a low-powered virtual machine, it should work though it will take some time. There were no issues on a VPS with a single core and 1GB of RAM; if you are using an even more limited device and run into issues, you can try creating a swapfile or use a more powerful machine running Gentoo to [cross build](https://wiki.gentoo.org/wiki/Cross_build_environment). If you have a wait ahead of you, now would be a good time to take a break, strech a bit, refresh your beverage of choice and/or get a snack, and reply to Arch users' posts with "I use Gentoo btw" as we do.
+
+### Install PostgreSQL
+
+[Gentoo  Wiki article](https://wiki.gentoo.org/wiki/PostgreSQL) as well as [PostgreSQL QuickStart](https://wiki.gentoo.org/wiki/PostgreSQL/QuickStart) might be worth a quick glance, as the way Gentoo handles postgres is slightly unusual, with built in capability to have two different databases running for testing and live or whatever other purpouse. While it is still straightforward to install, it does mean that the version numbers used in this guide might change for future updates, so keep an eye out for the output you get from `emerge` to ensure you are using the correct ones.
+
+* Install postgresql if you have not done so already:
+
+```shell
+ # emerge --ask dev-db/postgresql
+```
+
+Ensure that `/etc/conf.d/postgresql-11` has the encoding you want (it defaults to UTF8 which is probably what you want) and make any adjustments to the data directory if you find it necessary. Be sure to adjust the number at the end depending on what version of postgres you actually installed.
+
+* Initialize the database cluster
+
+The output from emerging postgresql should give you a command for initializing the postgres database. The default slot should be indicated in this command, ensure that it matches the command below.
+
+```shell
+ # emerge --config dev-db/postgresql:11
+```
+
+* Start postgres and enable the system service
+ 
+```shell
+ # /etc/init.d/postgresql-11 start
+ # rc-update add postgresql-11 default
+ ```
+ 
+### A note on licenses, the AGPL, and deployment procedures
+
+If you do not plan to make any modifications to your Pleroma instance, cloning directly from the main repo will get you what you need. However, if you plan on doing any contributions to upstream development, making changes or modifications to your instance, making custom themes, or want to play around--and let's be honest here, if you're using Gentoo that is most likely you--you will save yourself a lot of headache later if you take the time right now to fork the Pleroma repo and use that in the following section.
+
+Not only does this make it much easier to deploy changes you make, as you can commit and pull from upstream and all that good stuff from the comfort of your local machine then simply `git pull` on your instance server when you're ready to deploy, it also ensures you are compliant with the Affero General Public Licence that Pleroma is licenced under, which stipulates that all network services provided with modified AGPL code must publish their changes on a publicly available internet service and for free. It also makes it much easier to ask for help from and provide help to your fellow Pleroma admins if your public repo always reflects what you are running because it is part of your deployment procedure.
+
+### Install PleromaBE
+
+* Add a new system user for the Pleroma service and set up default directories:
+
+Remove `,wheel` if you do not want this user to be able to use `sudo`, however note that being able to `sudo` as the `pleroma` user will make finishing the insallation and common maintenence tasks somewhat easier:
+
+```shell
+ # useradd -m -G users,wheel -s /bin/bash pleroma
+```
+
+Optional: If you are using sudo, review your sudo setup to ensure it works for you. The `/etc/sudoers` file has a lot of options and examples to help you, and [the Gentoo sudo guide](https://wiki.gentoo.org/wiki/Sudo) has more information. Finishing this installation will be somewhat easier if you have a way to sudo from the `pleroma` user, but it might be best to not allow that user to sudo during normal operation, and as such there will be a reminder at the end of this guide to double check if you would like to lock down the `pleroma` user after initial setup.
+
+**Note**: To execute a single command as the Pleroma system user, use `sudo -Hu pleroma command`. You can also switch to a shell by using `sudo -Hu pleroma $SHELL`. If you don't have or want `sudo` or would like to use the system as the `pleroma` user for instance maintenance tasks, you can simply use `su - pleroma` to switch to the `pleroma` user.
+
+* Git clone the PleromaBE repository and make the Pleroma user the owner of the directory:
+
+It is highly recommended you use your own fork for the `https://path/to/repo` part below, however if you foolishly decide to forego using your own fork, the primary repo `https://git.pleroma.social/pleroma/pleroma` will work here.
+
+```shell
+ pleroma$ cd ~
+ pleroma$ git clone https://path/to/repo
+```
+
+* Change to the new directory:
+
+```shell
+pleroma$ cd ~/pleroma
+```
+
+* Install the dependencies for Pleroma and answer with `yes` if it asks you to install `Hex`:
+
+```shell
+pleroma$ mix deps.get
+```
+
+* Generate the configuration:
+
+```shell
+pleroma$ mix pleroma.instance gen
+```
+
+  * Answer with `yes` if it asks you to install `rebar3`.
+
+  * This part precompiles some parts of Pleroma, so it might take a few moments
+
+  * After that it will ask you a few questions about your instance and generates a configuration file in `config/generated_config.exs`.
+
+  * Spend some time with `generated_config.exs` to ensure that everything is in order. If you plan on using an S3-compatible service to store your local media, that can be done here. You will likely mostly be using `prod.secret.exs` for a production instance, however if you would like to set up a development environment, make a copy to `dev.secret.exs` and adjust settings as needed as well.
+
+```shell
+pleroma$ mv config/generated_config.exs config/prod.secret.exs
+```
+
+* The previous command creates also the file `config/setup_db.psql`, with which you can create the database. Ensure that it is using the correct database name on the `CREATE DATABASE` and the `\c` lines, then run the postgres script:
+
+```shell
+pleroma$ sudo -Hu postgres psql -f config/setup_db.psql
+```
+
+* Now run the database migration:
+
+```shell
+pleroma$ MIX_ENV=prod mix ecto.migrate
+```
+
+* Now you can start Pleroma already
+
+```shell
+pleroma$ MIX_ENV=prod mix phx.server
+```
+
+It probably won't work over the public internet quite yet, however, as we still need to set up a web servere to proxy to the pleroma application, as well as configure SSL.
+
+### Finalize installation
+
+Assuming you want to open your newly installed federated social network to, well, the federation, you should run nginx or some other webserver/proxy in front of Pleroma. It is also a good idea to set up Pleroma to run as a system service.
+
+#### Nginx
+
+* Install nginx, if not already done:
+
+```shell
+ # emerge --ask www-servers/nginx
+```
+
+* Create directories for available and enabled sites:
+
+```shell
+ # mkdir -p /etc/nginx/sites-{available,enabled}
+```
+
+* Append the following line at the end of the `http` block in `/etc/nginx/nginx.conf`:
+
+```Nginx
+include sites-enabled/*;
+```
+
+* Setup your SSL cert, using your method of choice or certbot. If using certbot, install it if you haven't already:
+
+```shell
+ # emerge --ask app-crypt/certbot app-crypt/certbot-nginx
+```
+
+and then set it up:
+
+```shell
+ # mkdir -p /var/lib/letsencrypt/
+ # certbot certonly --email <your@emailaddress> -d <yourdomain> --standalone
+```
+
+If that doesn't work the first time, add `--dry-run` to further attempts to avoid being ratelimited as you identify the issue, and do not remove it until the dry run succeeds. If that doesn’t work, make sure, that nginx is not already running. If it still doesn’t work, try setting up nginx first (change ssl “on” to “off” and try again). Often the answer to issues with certbot is to use the `--nginx` flag once you have nginx up and running.
+
+If you are using any additional subdomains, such as for a media proxy, you can re-run the same command with the subdomain in question. When it comes time to renew later, you will not need to run multiple times for each domain, one renew will handle it.
+
+---
+
+* Copy the example nginx configuration and activate it:
+
+```shell
+ # cp /home/pleroma/pleroma/installation/pleroma.nginx /etc/nginx/sites-available/
+ # ln -s /etc/nginx/sites-available/pleroma.nginx /etc/nginx/sites-enabled/pleroma.nginx
+```
+
+* Take some time to ensure that your nginx config is correct
+
+Replace all instances of `example.tld` with your instance's public URL. If for whatever reason you made changes to the port that your pleroma app runs on, be sure that is reflected in your configuration.
+
+Pay special attention to the line that begins with `ssl_ecdh_curve`. It is stongly advised to comment that line out so that OpenSSL will use its full capabilities, and it is also possible you are running OpenSSL 1.0.2 necessitating that you do this.
+
+* Enable and start nginx:
+
+```shell
+ # rc-update add nginx default
+ # /etc/init.d/nginx start
+```
+
+If you are using certbot, it is HIGHLY recommend you set up a cron job that renews your certificate, and that you install the suggested `certbot-nginx` plugin. If you don't do these things, you only have yourself to blame when your instance breaks suddenly because you forgot about it.
+
+First, ensure that the command you will be installing into your crontab works.
+
+```shell
+ # /usr/bin/certbot renew --nginx
+```
+
+Assuming not much time has passed since you got certbot working a few steps ago, you should get a message for all domains you installed certificates for saying `Cert not yet due for renewal`. 
+
+Now, run crontab as a superuser with `crontab -e` or `sudo crontab -e` as appropriate, and add the following line to your cron:
+
+```cron
+0 0 1 * * /usr/bin/certbot renew --nginx
+```
+
+This will run certbot on the first of the month at midnight. If you'd rather run more frequently, it's not a bad idea, feel free to go for it.
+
+#### Other webserver/proxies
+
+If you would like to use other webservers or proxies, there are example configurations for some popular alternatives in `/home/pleroma/pleroma/installation/`. You can, of course, check out [the Gentoo wiki](https://wiki.gentoo.org) for more information on installing and configuring said alternatives.
+
+#### Create the uploads folder
+
+Even if you are using S3, Pleroma needs someplace to store media posted on your instance. If you are using the `/home/pleroma/pleroma` root folder suggested by this guide, simply:
+
+```shell
+ pleroma$ mkdir -p ~/pleroma/uploads
+ ```
+
+#### init.d service
+
+* Copy example service file
+
+```shell
+ # cp /home/pleroma/pleroma/installation/init.d/pleroma /etc/init.d/
+```
+
+* Be sure to take a look at this service file and make sure that all paths fit your installation
+
+* Enable and start `pleroma`:
+
+```shell
+ # rc-update add pleroma default
+ # /etc/init.d/pleroma start
+```
+
+#### Create your first user
+
+If your instance is up and running, you can create your first user with administrative rights with the following task:
+
+```shell
+pleroma$ MIX_ENV=prod mix pleroma.user new <username> <your@emailaddress> --admin
+```
+
+#### Privilege cleanup
+
+If you opted to allow sudo for the `pleroma` user but would like to remove the ability for greater security, now might be a good time to edit `/etc/sudoers` and/or change the groups the `pleroma` user belongs to. Be sure to restart the pleroma service afterwards to ensure it picks up on the changes.

 # Introduction to Pleroma
-**What is Pleroma?**  
+## What is Pleroma?
 Pleroma is a federated social networking platform, compatible with GNU social, Mastodon and other OStatus and ActivityPub implementations. It is free software licensed under the AGPLv3.  
 It actually consists of two components: a backend, named simply Pleroma, and a user-facing frontend, named Pleroma-FE. It also includes the Mastodon frontend, if that's your thing.  
 It's part of what we call the fediverse, a federated network of instances which speak common protocols and can communicate with each other.  
 One account on a instance is enough to talk to the entire fediverse!

+  generate an emoji file list for you.
+
+  The manifest entry will either be written to a newly created
+  `index.json` file or appended to the existing one, *replacing*
+  the old pack with the same name if it was in the file previously.
+
+  The file list will be written to the file specified previously,
+  *replacing* that file. You _should_ check that the file list doesn't
+  contain anything you don't need in the pack, that is, anything that is
+  not an emoji (the whole pack is downloaded, but only emoji files
