2. Review the `CONTRIBUTING.md` guidelines if you plan to contribute
3. Follow the setup instructions in `Development.md`
4. Dive into specific component documentation based on your area of interest:
   - Frontend developers should focus on `/frontend/README.md`
   - Backend developers should start with `/openhands/README.md`
