+## FAQ
+
+### Is this an Astro integration?
+
+No. It is framework-agnostic Node scripts plus Astro wiring guides and an example. Anything with a Markdown directory and a Node build step works: Astro, Eleventy, Hugo, Next.js static export.
+
+### Does llms.txt improve Google rankings?
+
+No. Google ignores `llms.txt`; it serves Claude, GPT, Perplexity and other agents. For Google, prioritize sitemap submission, real indexation, one valid JSON-LD block per page, and quotable content.
+
+### How is this different from astro-seo?
+
+`astro-seo` is a meta-tags component for your `<head>`. This toolkit generates the files around it — `llms.txt`, `llms-full.txt`, `sitemap.xml`, `robots.txt` — plus JSON-LD builders, IndexNow submission, a dist validator, and an agent skill that wires it all up.
+
+### Can my AI agent install and use this?
+
+Yes. `npx skills add RelayStack/astro-seo-toolkit --skill astro-seo`, or copy `skills/astro-seo/` into any harness skills dir, or run everything via `npx -y github:RelayStack/astro-seo-toolkit <command>` with no install.
