Add llms.txt file

[gkorland]

• Add an llms.txt file
  Create a /llms.txt file at your site root that summarizes your documentation structure for AI tools. This is the single most impactful thing you can do for AI readability.

• Fix your llms.txt format
  Your llms.txt should have an H1 title, a blockquote description, H2 sections, and list items with links. Follow the llmstxt.org specification.

• Add descriptions to your links
  Each link in your llms.txt should include a colon-separated description, e.g., '- Auth: How to authenticate with API keys'. This helps AI understand what each page covers without loading it.

• Add an Optional section
  Add a '## Optional' section to your llms.txt for secondary content like changelogs and migration guides. This helps AI prioritize what to read within its context window.

• Add a clear product description
  Your llms.txt blockquote should clearly describe what your product does in 10+ words. Don't make AI guess — be explicit.

• List key constraints and requirements
  Add notes about authentication requirements, rate limits, prerequisites, and version compatibility in the opening section of your llms.txt.
