-Delta is the API server for the Revolt platform.
+</div>
+<br/>
 
-**Features:**
+## Minimum Supported Rust Version
 
-- Robust and efficient API routes for running a chat platform.
-- Distributed notification system, allowing any node to be seamlessly connected.
-- Simple deployment, based mostly on pure Rust code and libraries.
-- Hooks up to a MongoDB deployment, provide URI and no extra work needed.
+Rust 1.76 or higher.
 
-## Stack
+> [!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).

+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"
+> ```
+
+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
+# run the events server
+cargo run --bin revolt-bonfire
+# run the file server
+cargo run --bin revolt-autumn
+# run the proxy server
+cargo run --bin revolt-january
+# run the push daemon (not usually needed in regular development)
+cargo run --bin revolt-pushd
+
+# hint:
+# mold -run <cargo build, cargo run, etc...>
+# mold -run ./scripts/start.sh
+```
+
+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
+```

+# Code Style Guide
+
+Beyond using Cargo format and Clippy, there are some specific code style guidelines laid out in this document for different parts of the project.
+
+## Writing Style
+
+- Shorten "identifier" to "Id" with that exact casing, i.e. Server Id.
+
+## `core/database` crate
+
+w.r.t. `model.rs` files
+
+- All struct definitions must be commented.
+  ```rust
+  /// Server
+  pub struct Server {
+    /// Name of the server
+    pub name: String,
+  ```
+- Struct definitions should not include derives unless necessary (if additional traits such as Hash are required) and instead use `auto_derived!` and `auto_derived_partial!`.
+  ```rust
+  auto_derived_partial!(
+    /// Server
+    pub struct Server { .. },
+    "PartialServer"
+  );
+  ```
+- `auto_derived!` macro accepts multiple entries and should be used as such:
+
+  ```rust
+  auto_derived!(
+    /// Optional fields on server object
+    pub enum FieldsServer { .. }
+
+    /// Optional fields on server object
+    pub enum FieldsRole { .. }
+  );
+  ```
+
+- If special serialisation conditions are required, such as checking if a boolean is false, use the existing definitions for these functions from the crate root:
+  ```rust
+  #[serde(skip_serializing_if = "crate::if_false", default)]
+  ```
+- `impl` blocks may be defined below the struct definitions and should be ordered in the same order of definition. Methods in the block must follow the same guidelines as traits where-in: methods are ordered in terms of CRUD, there are empty line breaks, and methods are commented.
+
+w.r.t. `ops` module for models
+
+- All traits must use a the name format `AbstractPlural` where Plural is the plural form of the collection. e.g. Servers
+- Traits defined must follow these guidelines:
+
+  - Methods are ordered in terms of CRUD, create-read-update-delete ordering.
+
+    ```rust
+    #[async_trait]
+    pub trait AbstractServerMembers: Sync + Send {
+      /// Insert a new server member into the database
+      async fn insert_member(&self, member: &Member) -> Result<()>;
+
+      /// Fetch a server member by their id
+      async fn fetch_member(&self, server_id: &str, user_id: &str) -> Result<Member>;
+
+      /// Update information for a server member
+      async fn update_member(&self, .. ) -> Result<()>;
+
+      /// Delete a server member by their id
+      async fn delete_member(&self, id: &MemberCompositeKey) -> Result<()>;
+    }
+    ```
+
+  - There should be an empty line break between each method declaration.
+  - All methods must have an appropriate comment.
+
+- When implementing the trait defined in `ops.rs` with each driver, the method declaration style should be the same for ease of searching: same ordering, same comments, same line breaks.

+# 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/).
