 This repository contains the sources for the Space ROS documentation which is hosted as: https://space-ros.github.io/docs
 The sources from this repository are built by GitHub Actions.
 
+## Quick Start with Pixi
+
+This project uses [Pixi](https://pixi.sh) for dependency management and task running. To get started:
+
+1. **Install Pixi** (if not already installed):
+   Follow the installation instructions at https://pixi.sh
+
+2. **Install dependencies**:
+   ```bash
+   pixi install
+   ```
+
+3. **Build documentation**:
+   ```bash
+   # Build single version
+   pixi run html
+
+   # Build multi-version (for deployment)
+   pixi run multiversion
+   ```
+
+4. **Run tests**:
+   ```bash
+   pixi run test
+   ```
+
+5. **Serve locally** (optional):
+   ```bash
+   pixi run serve
+   ```
+
+## Available Commands
+
+| Command | Description |
+|---------|-------------|
+| `pixi run html` | Build single version documentation |
+| `pixi run multiversion` | Build multi-version documentation |
+| `pixi run test` | Run doc8 linting tests |
+| `pixi run clean` | Clean build directory |
+| `pixi run serve` | Serve documentation locally |
+| `pixi run ci` | Run CI workflow (test + build) |
+| `pixi run deploy` | Run deployment workflow (test + multiversion) |
+
+
+
 ## Contributing to the documentation
 
 Contributions to this site are most welcome.
 Please see the [Contributing to ROS 2 Documentation](https://docs.ros.org/en/rolling/The-ROS2-Project/Contributing/Contributing-To-ROS-2-Documentation.html) page to learn more.
 Most of the guidelines there apply but the branch structure is much simpler as Space ROS currently has only one supported distribution.
 
+### Development Workflow
+
+1. Fork and clone the repository
+2. Install dependencies: `pixi install`
+3. Make your changes to the documentation
+4. Test your changes: `pixi run test`
+5. Build and preview: `pixi run html && pixi run serve`
+6. Submit a pull request
+
