+# Contributing to Wef
+
+Thank you for your interest in contributing to Wef! This document provides guidelines and information for contributors.
+
+## Prerequisites
+
+Before you can build and test Wef, you'll need:
+
+## Development Setup
+
+1. **Clone the repository**
+
+   ```bash
+   git clone https://github.com/longbridge/wef.git
+   cd wef
+   ```
+
+2. **Install cargo-wef**
+
+   ```bash
+   cargo install --path cargo-wef
+   ```
+
+3. **Initialize CEF**
+
+   ```bash
+   cargo wef init
+   ```
+
+   This downloads the Chromium Embedded Framework binaries to `~/.cef`
+
+## Building and Testing
+
+### Building
+
+```bash
+# Build everything
+cargo wef build
+
+# Build specific components
+cargo build -p wef           # Core library
+cargo build -p cargo-wef     # CLI tool
+```
+
+### Testing
+
+```bash
+# Run all tests
+cargo test --all
+
+# Test specific components
+cargo test -p wef
+cargo test -p cargo-wef
+```
+
+### Running Examples
+
+```bash
+cargo wef run -p wef-example
+```
+
+## Development Tips
+
+### CEF Troubleshooting
+
+If you encounter CEF-related build issues:
+
+1. **Clear CEF cache**
+
+   ```bash
+   rm -rf ~/.cef
+   cargo wef init
+   ```
+
+2. **Check CEF version**
+   The CEF version is defined in `.github/workflows/ci.yml`
+
+3. **Verify system dependencies**
+   Ensure all required system packages are installed
+
+### Debugging
+
+- Use `cargo wef run -p wef-winit` to test changes quickly
+- Enable debug logging with `RUST_LOG=debug`
+- Use the debugger-friendly debug profile for development
+
+## Getting Help
+
+- **Documentation**: Check the [README](README.md) and [library docs](wef/README.md)
+- **Issues**: Search existing [GitHub issues](https://github.com/longbridge/wef/issues)
+- **Discussions**: Use [GitHub Discussions](https://github.com/longbridge/wef/discussions) for questions
