The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. ### Option 2 — Browse the documentation index Full index: https://docs.linuxfoundation.org/lfx/sitemap.md Use this to discover valid page paths or navigate the documentation structure. ### Option 3 — Retrieve the full documentation corpus Full export: https://docs.linuxfoundation.org/lfx/llms-full.txt Use this to access all content at once and perform your own parsing or retrieval. It will be more expensive. ## Tips for requesting documentation Prefer `.md` URLs for structured content, append `.md` to URLs (e.g., `/lfx/project-control-center/v1-prior-version/release-notes/pcc-march-15-2022-release.md`). You may also use `Accept: text/markdown` header for content negotiation.
