The README is the project's front door
A useful README tells a new developer or user what the project does, how to install it, how to run it and where to find important documentation.
Recommended structure
For many projects, include a project overview, features, requirements, installation, configuration, usage examples, testing instructions and contribution guidance. Add screenshots or architecture diagrams when they materially improve understanding.
Keep documentation executable
Commands shown in the README should match the actual project. Outdated setup instructions damage trust quickly, so update documentation when the development workflow changes.
