+## Unreleased
+
+### Added
+- Prometheus metrics exporting from `/api/v1/akkoma/metrics`
+- Ability to alter http pool size
+- Translation of statuses via ArgosTranslate
+- Argon2 password hashing
+- Ability to "verify" links in profile fields via rel=me
+- Mix tasks to dump/load config to/from json for bulk editing
+- Followed hashtag list at /api/v1/followed\_tags, API parity with mastodon
+- Ability to set posting language in the post form, API parity with mastodon
+- Ability to match domains in MRF by a trailing wildcard
+  - Currently supported formats:
+    - `example.com` (implicitly matches `*.example.com`)
+    - `*.example.com`
+    - `example.*` (implicitly matches `*.example.*`)
+
+### Removed
+- Non-finch HTTP adapters
+- Legacy redirect from /api/pleroma/admin to /api/v1/pleroma/admin
+- Legacy redirects from /api/pleroma to /api/v1/pleroma
+- :crypt dependency
+
+### Changed
+- Return HTTP error 413 when uploading an avatar or banner that's above the configured upload limit instead of a 500.
+- Non-admin users now cannot register `admin` scope tokens (not security-critical, they didn't work before, but you _could_ create them)
+  - Admin scopes will be dropped on create
+- Rich media will now backoff for 20 minutes after a failure
+- Quote posts are now considered as part of the same thread as the post they are quoting
+- Extend the mix task `prune_objects` with options to keep more relevant posts
+- Simplified HTTP signature processing
+- Rich media will now hard-exit after 5 seconds, to prevent timeline hangs
+- HTTP Content Security Policy is now far more strict to prevent any potential XSS/CSS leakages
+- Follow requests are now paginated, matches mastodon API spec, so use the Link header to paginate.
+- `internal.fetch` and `relay` actors are now represented with the actor type `Application`
+
+### Fixed 
+- /api/v1/accounts/lookup will now respect restrict\_unauthenticated
+- Unknown atoms in the config DB will no longer crash akkoma on boot
+
+### Upgrade notes
+- Ensure `config :tesla, :adapter` is either unset, or set to `{Tesla.Adapter.Finch, name: MyFinch}` in your .exs config
+- Pleroma-FE will need to be updated to handle the new /api/v1/pleroma endpoints for  custom emoji

+# Monitoring Akkoma
+
+If you run akkoma, you may be inclined to collect metrics to ensure your instance is running smoothly,
+and that there's nothing quietly failing in the background.
+
+To facilitate this, akkoma exposes prometheus metrics to be scraped.
+
+## Prometheus
+
+See: [export\_prometheus\_metrics](../../configuration/cheatsheet#instance)
+
+To scrape prometheus metrics, we need an oauth2 token with the `admin:metrics` scope.
+
+consider using [constanze](https://akkoma.dev/AkkomaGang/constanze) to make this easier -
+
+```bash
+constanze token --client-app --scopes "admin:metrics" --client-name "Prometheus"
+```
+
+or see `scripts/create_metrics_app.sh` in the source tree for the process to get this token.
+
+Once you have your token of the form `Bearer $ACCESS_TOKEN`, you can use that in your prometheus config:
+
+```yaml
+- job_name: akkoma
+  scheme: https
+  authorization:
+    credentials: $ACCESS_TOKEN # this should have the bearer prefix removed
+  metrics_path: /api/v1/akkoma/metrics

+## Stealing emoji
+
+Managing your emoji can be hard work, and you just want to have the cool emoji your friends use? As usual, crime comes to the rescue!
+
+You can use the `Pleroma.Web.ActivityPub.MRF.StealEmojiPolicy` [Message Rewrite Facility](../configuration/cheatsheet.md#mrf) to automatically add to your instance emoji that messages from specific servers contain. Note that this happens on message processing, so the emoji will be added only after your instance receives some interaction containing emoji _after_ configuring this.
+
+To activate this you have to [configure](../configuration/cheatsheet.md#mrf_steal_emoji) it in your configuration file. For example if you wanted to steal any emoji that is not related to cinnamon and not larger than about 10K from `coolemoji.space` and `spiceenthusiasts.biz`, you would add the following:
+```elixir
+config :pleroma, :mrf,
+  policies: [
+    Pleroma.Web.ActivityPub.MRF.StealEmojiPolicy
+  ]
+
+config :pleroma, :mrf_steal_emoji,
+  hosts: [
+    "coolemoji.space",
+    "spiceenthusiasts.biz"
+  ],
+  rejected_shortcodes: [
+    ".*cinnamon.*"
+  ],
+  size_limit: 10000
+```
+
+Note that this may not obey emoji licensing restrictions. It's extremely unlikely that anyone will care, but keep this in mind for when Nintendo starts their own instance.

 When PostgreSQL receives a query, it decides on a strategy for searching the requested data, this is called a query plan. The query planner has two modes: generic and custom. Generic makes a plan for all queries of the same shape, ignoring the parameters, which is then cached and reused. Custom, on the contrary, generates a unique query plan based on query parameters.

+# Contributing to Akkoma
+
+You wish to add a new feature in Akkoma, but don't know how to proceed? This guide takes you through the various steps of the development and contribution process.
+
+If you're looking for stuff to implement or fix, check the [bug-tracker](https://akkoma.dev/AkkomaGang/akkoma/issues) or [forum](https://meta.akkoma.dev/c/requests/5).
+
+Come say hi to us in the [#akkoma-dev chat room](./../#irc)!
+
+## Akkoma Clients
+
+Akkoma is the back-end. Clients have their own repositories and often separate projects. You can check what clients work with Akkoma [on the clients page](../clients/). If you maintain a working client not listed yet, feel free to make a PR [to these docs](./#docs)!
+
+For resources on APIs and such, check the sidebar of this page.
+
+## Docs
+
+The docs are written in Markdown, including certain extensions, and can be found [in the docs folder of the Akkoma repo](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/docs/). The content itself is stored in the `docs` subdirectory.
+
+## Technology
+
+Akkoma is written in [Elixir](https://elixir-lang.org/) and uses [Postgresql](https://www.postgresql.org/) for database. We use [Git](https://git-scm.com/) for collaboration and tracking code changes. Furthermore it can typically run on [Unix and Unix-like OS'es](https://en.wikipedia.org/wiki/Unix-like). For development, you should use an OS which [can run Akkoma](../installation/debian_based_en/).
+
+It's good to have at least some basic understanding of at least Git and Elixir. If this is completely new for you, there's some [videos explaining Git](https://git-scm.com/doc) and Codeberg has a nice article explaining the typical [pull requests Git flow](https://docs.codeberg.org/collaborating/pull-requests-and-git-flow/). For Elixir, you can follow Elixir's own [Getting Started guide](https://elixir-lang.org/getting-started/introduction.html).
+
+## Setting up a development environment
+
+The best way to start is getting the software to run from source so you can start poking on it. Check out the [guides for setting up an Akkoma instance for development](setting_up_akkoma_dev/#setting-up-a-akkoma-development-environment).
+
+## General overview
+### Modules
+
+Akkoma has several modules. There are modules for [uploading](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/uploaders), [upload filters](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/upload/filter), [translators](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/akkoma/translators)... The most famous ones are without a doubt the [MRF policies](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/web/activity_pub/mrf). Modules are often self contained and a good way to start with development because you don't have to think about much more than just the module itself. We even have an example on [writing your own MRF policy](/configuration/mrf/#writing-your-own-mrf-policy)!
+
+Another easy entry point is the [mix tasks](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/mix/tasks/pleroma). They too are often self contained and don't need you to go through much of the code.
+
+### Activity Streams/Activity Pub
+
+Akkoma uses Activity Streams for both federation, as well as internal representation. It may be interesting to at least go over the specifications of [Activity Pub](https://www.w3.org/TR/activitypub/), [Activity Streams 2.0](https://www.w3.org/TR/activitystreams-core/), and [Activity Streams Vocabulary](https://www.w3.org/TR/activitystreams-vocabulary/). Note that these are not enough to have a full grasp of how everything works, but should at least give you the basics to understand how messages are passed between and inside Akkoma instances.
+
+## Don't forget
+
+When you make changes, you're expected to create [a Pull Request](https://akkoma.dev/AkkomaGang/akkoma/pulls). You don't have to wait until you finish to create the PR, but please do prefix the title of the PR with "WIP: " for as long as you're still working on it. The sooner you create your PR, the sooner people know what you are working on and the sooner you can get feedback and, if needed, help. You can then simply keep working on it until you are finished.
+
+When doing changes, don't forget to add it to the relevant parts of the [CHANGELOG.md](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/CHANGELOG.md).
+
+You're expected to write [tests](https://elixirschool.com/en/lessons/testing/basics). While code is generally stored in the `lib` directory, tests are stored in the `test` directory using a similar folder structure. Feel free to peak at other tests to see how they are done. Obviously tests are expected to pass and properly test the functionality you added. If you feel really confident, you could even try to [write a test first and then write the code needed to make it pass](https://en.wikipedia.org/wiki/Test-driven_development)!
+
+Code is formatted using the default formatter that comes with Elixir. You can format a file with e.g. `mix format /path/to/file.ex`. To check if everything is properly formatted, you can run `mix format --check-formatted`.

 ## Working on multiple branches
 
-If you develop on a separate branch, it's possible you did migrations that aren't merged into another branch you're working on. If you have multiple things you're working on, it's probably best to set up multiple Akkoma instances each with their own database. If you finished with a branch and want to switch back to develop to start a new branch from there, you can drop the database and recreate the database (e.g. by using `config/setup_db.psql`).
