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://julichaan.gitbook.io/julichaan-docs/sitemap.md Use this to discover valid page paths or navigate the documentation structure. ### Option 3 — Retrieve the full documentation corpus Full export: https://julichaan.gitbook.io/julichaan-docs/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., `/julichaan-docs/certifications/web-red-team-analyst-web-rta.md`). You may also use `Accept: text/markdown` header for content negotiation.
