+# Project structure
+
+## `attachments` and `images`
+
+They're empty folders on purpose. Litecord will write files to them to hold
+message attachments or avatars.
+
+## `manage`
+
+Contains the `manage.py` script's main function, plus all the commands.
+A point of interest is the `manage/cmd/migration/scripts` folder, as they hold
+all the SQL scripts required for migrations.
+
+## `litecord`
+
+The folder + `run.py` contain all of the backend's source code. The backend runs
+Quart as its HTTP server, and a `websockets` server for the Gateway.
+
+ - `litecord/blueprints` for everything HTTP related. 
+ - `litecord/gateway` for main things related to the websocket or the Gateway.
+ - `litecord/embed` contains code related to embed sanitization, schemas, and
+    mediaproxy contact.
+ - `litecord/ratelimits` hold the ratelimit implementation copied from
+    discord.py plus a simple manager to hold the ratelimit objects. a point of
+    interest is `litecord/ratelimits/handler.py` that holds the main thing.
+ - `litecord/pubsub` is defined on `docs/pubsub.md`.
+ - `litecord/voice` holds the voice implementation, LVSP client, etc.
+
+There are other files around `litecord/`, e.g the snowflake library, presence/
+image/job managers, etc.
+
+## `static`
+
+Holds static files, such as a basic index page and the `invite_register.html`
+page.
+
+## `tests`
+
+Tests are run with `pytest` and the asyncio plugin for proper testing. A point
+of interest is `tests/conftest.py` as it contains test-specific configuration
+for the app object. Adding a test is trivial, as pytest will match against any
+file containing `test_` as a prefix.
