+# Contributing to RustFS Flake
+
+First off, thank you for considering contributing to RustFS! It's people like you that make RustFS such a great tool.
+
+## Development Workflow
+
+This repository manages the Nix Flake for prebuilt RustFS binaries.
+
+### Prerequisites
+
+- [Nix](https://nixos.org/download.html) with Flakes enabled.
+- [nixpkgs-fmt](https://github.com/nix-community/nixpkgs-fmt) for code formatting.
+
+### Local Testing
+
+Before submitting a PR, please ensure your changes are valid:
+
+```bash
+# Format check
+nix shell nixpkgs#nixpkgs-fmt -c nixpkgs-fmt --check .
+
+# Syntax and basic flake check
+nix flake check
+
+# Build the default package for your system
+nix build .#default
+
+# Test the example configuration
+cd examples && nix eval .#nixosConfigurations.example-host.config.services.rustfs
+```
+
+### Updating Binaries
+
+The `sources.json` file tracks the upstream versions and hashes. When a new version of RustFS is released:
+
+1. Update the `version` field in `sources.json`.
+2. Update the `sha256` hashes for all supported platforms.
+3. Verify the build: `nix build .`.
+
+## Coding Standards
+
+- **Nix Style**: Follow the [Nixpkgs architecture](https://nixos.org/manual/nixpkgs/stable/) guidelines.
+- **Modularity**: Keep the NixOS module (`nixos/rustfs.nix`) decoupled from the package definition.
+- **Documentation**: Any new option in the NixOS module must include a clear `description`.
+
+## Pull Request Process
+
+1. Create a new branch: `git checkout -b feat/your-feature-name`.
+2. Commit your changes using [Conventional Commits](https://www.conventionalcommits.org/) (e.g., `feat: add tlsDirectory option`).
+3. Ensure the `examples/` are updated if you change the module interface.
+4. Submit the PR and wait for the maintainers' review.
+
+## Security
+
+If you discover a security vulnerability, please do **not** open an issue. Instead, contact the maintainers directly using the contact options provided in this repository's hosting platform.
