 # Pleroma
 
+## About Pleroma
+
+Pleroma is an OStatus-compatible social networking server written in Elixir, compatible with GNU Social and Mastodon. It is high-performance and can run on small devices like a Raspberry Pi.
+
+No release has been made yet, but several servers have been online for months already. If you want to run your own server, feel free to contact us at @lain@pleroma.soykaf.com or in our dev chat at https://matrix.heldscal.la/#/room/#pleromafe:matrix.heldscal.la.

 ### Database setup
 
-  * You'll need to allow password-based authorisation for `postgres` superuser
+  * Create a database user and database for pleroma
-     * Changing default password for superuser is probably a good idea:
-        * Open psql shell as postgres user - while being root run `su postgres -c psql`
-        * There, enter following: 
-
-        ```sql
-        ALTER USER postgres with encrypted password '<PASSWORD>';
-        ``` 
-
-        where `<PASSWORD>` is any string, no need to manually encrypt it - postgres will encrypt it automatically for you.
-        * Replace password in file `config/dev.exs` with password you supplied in previous step (look for line like `password: "postgres"`)
-     
-     * Edit `/etc/postgresql/9.6/main/pg_hba.conf` (Assuming you have the 9.6 version) and change the line:
-
-     ```
-     local   all             postgres                                peer

-     ```
-
-     don't forget to revert it in the later step so you won't have to enter password when accessing psql console.
-  * Create and update your database with `mix ecto.create && mix ecto.migrate`. If it gives errors, try running again, this is a known issue.
-  * Undo changes you made in `/etc/postgresql/9.6/main/pg_hba.conf` (replace `md5` with `peer`)
-  * You most likely don't want having some application accessing database as a superuser, so you should create separate user for Pleroma. Right now it must be done manually (issue #27).

   * 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/
   On Debian you can use `certbot` package and command to manage letsencrypt certificates.
