Each topic below is a self-contained reference for a part of the app, with screenshots. Read the sections in order to learn the whole program, or search the sidebar to look one thing up.

The complete documentation is also one downloadable Markdown file, rayrf-docs.md, for offline reading or for loading into agentic tools that drive RayRF headless or through the CLI (Pro required for headless and CLI use).
