-Rust 1.70 or higher.
+Rust 1.86.0 or higher.
 
-## Contributing
+> [!CAUTION]
+> The events server has a significant performance regression between Rust 1.77.2 and 1.78.0 onwards, see [issue #341](https://github.com/revoltchat/backend/issues/341). This is currently solved by build time options but we are looking for a proper fix.
 
-The contribution guide is located at [developers.revolt.chat/contributing](https://developers.revolt.chat/contributing).
-Please note that a pull request should only take care of one issue so that we can review it quickly.
+## Development Guide
+
+Before contributing, make yourself familiar with [our contribution guidelines](https://developers.revolt.chat/contrib.html) and the [technical documentation for this project](https://revoltchat.github.io/backend/).
+
+Before getting started, you'll want to install:
+
+- Rust toolchain (rustup recommended)
+- Docker
+- Git
+- mold (optional, faster compilation)
+
+> A **default.nix** is available for Nix users!
+> Just run `nix-shell` and continue.
+
+As a heads-up, the development environment uses the following ports:
+
+| Service                   |      Port      |
+| ------------------------- | :------------: |
+| MongoDB                   |     27017      |
+| Redis                     |      6379      |
+| MinIO                     |     14009      |
+| Maildev                   | 14025<br>14080 |
+| Revolt Web App            |     14701      |
+| RabbitMQ                  | 5672<br>15672  |
+| `crates/delta`            |     14702      |
+| `crates/bonfire`          |     14703      |
+| `crates/services/autumn`  |     14704      |
+| `crates/services/january` |     14705      |
+
+Now you can clone and build the project:
+
+```bash
+git clone https://github.com/revoltchat/backend revolt-backend
+cd revolt-backend
+cargo build
+```
+
+A default configuration `Revolt.toml` is present in this project that is suited for development.
+
+If you'd like to change anything, create a `Revolt.overrides.toml` file and specify relevant variables.
+
+> [!TIP]
+> Use Sentry to catch unexpected service errors:
+>
+> ```toml
+> # Revolt.overrides.toml
+> [sentry]
+> api = "https://abc@your.sentry/1"
+> events = "https://abc@your.sentry/1"
+> files = "https://abc@your.sentry/1"
+> proxy = "https://abc@your.sentry/1"
+> ```
+
+> [!TIP]
+> If you have port conflicts on common services, you can try the following:
+>
+> ```yaml
+> # compose.override.yml
+> services:
+>   redis:
+>     ports: !override
+>       - "14079:6379"
+>
+>   database:
+>     ports: !override
+>       - "14017:27017"
+>
+>   rabbit:
+>     ports: !override
+>       - "14072:5672"
+>       - "14672:15672"
+> ```
+>
+> And corresponding Revolt configuration:
+>
+> ```toml
+> # Revolt.overrides.toml
+> [database]
+> mongodb = "mongodb://127.0.0.1:14017"
+> redis = "redis://127.0.0.1:14079/"
+>
+> [rabbit]
+> port = 14072
+> ```
+
+Then continue:
+
+```bash
+# start other necessary services
+docker compose up -d
+
+# run everything together
+./scripts/start.sh
+# .. or individually
+# run the API server
+cargo run --bin revolt-delta

+You can start a web client by doing the following:
+
+```bash
+# if you do not have yarn yet and have a modern Node.js:
+corepack enable
+
+# clone the web client and run it:
+git clone --recursive https://github.com/revoltchat/revite
+cd revite
+yarn
+yarn build:deps
+echo "VITE_API_URL=http://local.revolt.chat:14702" > .env.local
+yarn dev --port 14701
+```
+
+Then go to http://local.revolt.chat:14701 to create an account/login.
+
+When signing up, go to http://localhost:14080 to find confirmation/password reset emails.
+
+## Deployment Guide
+
+### Cutting new crate releases
+
+Begin by bumping crate versions:
+
+```bash
+just patch # 0.0.X
+just minor # 0.X.0
+just major # X.0.0
+```
+
+Then commit the changes to package files.
+
+Proceed to publish all the new crates:
+
+```bash
+just publish
+```
+
+### Cutting new binary releases
+
+Tag and push a new release by running:
+
+```bash
+just release
+```
+
+If you have bumped the crate versions, proceed to [GitHub releases](https://github.com/revoltchat/backend/releases/new) to create a changelog.
+
+## Testing
+
+First, start the required services:
+
+```sh
+docker compose -f docker-compose.db.yml up -d
+```
+
+Now run tests for whichever database:
+
+```sh
+TEST_DB=REFERENCE cargo nextest run
+TEST_DB=MONGODB cargo nextest run
+```
