+## Development Guide
 
-## Contributing
+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/).
 
-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.
+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.
+
+Now you can clone and build the project:
+
+```bash
+git clone https://github.com/revoltchat/backend revolt-backend
+cd revolt-backend
+cargo build
+```
+
+If you want to run the API and event servers:
+
+```bash
+# create environment file (will be deprecated in future)
+cp .env.example .env
+
+# (optionally) copy the default configuration file
+cp crates/core/config/Revolt.toml Revolt.toml
+# configure as necessary...
+```
+
+You may want to copy the following configuration:
+
+```toml
+# Revolt.toml
+[database]
+mongodb = "mongodb://localhost"
+redis = "redis://localhost"
+
+[hosts]
+app = "http://local.revolt.chat"
+api = "http://local.revolt.chat:8000"
+events = "ws://local.revolt.chat:9000"
+autumn = "http://local.revolt.chat:3000"
+january = "http://local.revolt.chat:7000"
+voso_legacy = ""
+voso_legacy_ws = ""
+```
+
+Then continue:
+
+```bash
+# start other necessary services
+docker compose up -d
+
+# run the API server
+cargo run --bin revolt-delta
+# run the events server
+cargo run --bin revolt-bonfire
+
+# hint:
+# mold -run <cargo build, cargo run, etc...>
+```
+
+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
+yarn dev --port 3001
+```
+
+Then go to https://local.revolt.chat:3001
+
+## 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
+```
+

+# revolt.node
+
+**revolt.node:** Node.js bindings for the Revolt software
+
+This project was bootstrapped by [create-neon](https://www.npmjs.com/package/create-neon).
+
+## Building revolt.node
+
+Building revolt.node requires a [supported version of Node and Rust](https://github.com/neon-bindings/neon#platform-support).
+
+To run the build, run:
+
+```sh
+$ npm run build
+```
+
+This command uses the [@neon-rs/cli](https://www.npmjs.com/package/@neon-rs/cli) utility to assemble the binary Node addon from the output of `cargo`.
+
+## Exploring revolt.node
+
+After building revolt.node, you can explore its exports at the Node console:
+
+```sh
+$ npm i
+$ npm run build
+$ node
+> require('.').hello()
+'hello node'
+```
+
+## Available Scripts
+
+In the project directory, you can run:
+
+#### `npm install`
+
+Installs the project, including running `npm run build`.
+
+#### `npm run build`
+
+Builds the Node addon (`index.node`) from source, generating a release build with `cargo --release`.
+
+Additional [`cargo build`](https://doc.rust-lang.org/cargo/commands/cargo-build.html) arguments may be passed to `npm run build` and similar commands. For example, to enable a [cargo feature](https://doc.rust-lang.org/cargo/reference/features.html):
+
+```
+npm run build -- --feature=beetle
+```
+
+#### `npm run debug`
+
+Similar to `npm run build` but generates a debug build with `cargo`.
+
+#### `npm run cross`
+
+Similar to `npm run build` but uses [cross-rs](https://github.com/cross-rs/cross) to cross-compile for another platform. Use the [`CARGO_BUILD_TARGET`](https://doc.rust-lang.org/cargo/reference/config.html#buildtarget) environment variable to select the build target.
+
+#### `npm test`
+
+Runs the unit tests by calling `cargo test`. You can learn more about [adding tests to your Rust code](https://doc.rust-lang.org/book/ch11-01-writing-tests.html) from the [Rust book](https://doc.rust-lang.org/book/).
