Is there a document to systematically introduce what can raf do?

The motivation in wiki is not enough to let me know what exactly raf do. So do you have more detailed document or pulished paper?

Start by reviewing the existing wiki and repository documentation to identify what RAF capabilities are already explained. Done means adding or linking a more systematic introduction, or confirming that a published paper provides that overview; the issue does not name a specific documentation file or test.
