+## Architecture
+
+### Front end
+
+- The front end is written in `typescript`, using a react-like framework called [inferno](https://infernojs.org/). All UI elements are reusable `.tsx` components.
+- The front end repository is [lemmy-ui](https://github.com/LemmyNet/lemmy-ui).
+- The routes are at `src/shared/routes.ts`.
+- The components are located in `src/shared/components`.
+
+### Back end
+
+- The back end is written in `rust`, using `diesel`, and `actix`.
+- The server source code is split into main sections in `src`. These include:
+ - `db` - The low level database actions.
+ - Database additions are done using diesel migrations. Run `diesel migration generate xxxxx` to add new things.
+ - `api` - The high level user interactions (things like `CreateComment`)
+ - `routes` - The server endpoints .
+ - `apub` - The activitypub conversions.
+ - `websocket` - Creates the websocket server.
+
+## Linting / Formatting
+
+- Every front and back end commit is automatically formatted then linted using `husky`, and `lint-staged`.
+- Rust with `cargo fmt` and `cargo clippy`.
+- Typescript with `prettier` and `eslint`.
