+# LexAI website
+
+Marketing site for the LexAI monorepo: Home, Docs, Contribute, Community.
+
+## Develop
+
+```bash
+# from repo root
+npm run website:install
+npm run website:dev
+```
+
+Or inside this package:
+
+```bash
+npm install
+npm run dev
+```
+
+## Build
+
+```bash
+npm run website:build
+# → packages/website/dist/
+```
+
+Preview production build: `npm run website:preview`.
+
+Uses HashRouter so the site works on static hosts without server-side rewrite rules.
+
+## Deploy on Coolify
+
+This package is a **static** Vite build (`dist/`). No LexAI API keys or env vars.
+
+1. In Coolify: **+ New** → **Resource** → **Private Repository (with deploy key)** (Gitea).
+2. Repo SSH URL, for example `git@git.juankibin.space:kibin/LexAI.git`. If Gitea SSH is not on port 22, use `ssh://git@git.juankibin.space:PORT/kibin/LexAI.git` (Coolify sometimes needs `ssh:///` with three slashes).
+3. Add Coolify’s public deploy key to the Gitea repo: **Settings → Deploy / Access Keys** (read-only).
+4. Branch: `dev` or `main`.
+5. **Build Pack:** Nixpacks.
+6. **Base Directory:** `/packages/website` — required. Root `npm run build` builds Chrome, not this site.
+7. Enable **Is it a static site?**
+8. **Publish Directory:** `/dist`
+9. **Install command** (if the build says `vite: not found`): `npm ci` (do not omit devDependencies — Vite lives there).
+10. Optional env: `NIXPACKS_NODE_VERSION=22`
+11. Optional **Watch Paths:** `packages/website` so Chrome/VS Code/CLI commits do not redeploy.
+12. Set the domain, **Deploy**, then open `https://your-domain/#/docs`.
+
+Auto-deploy: Coolify resource → **Webhooks** → copy the URL + secret into Gitea **Settings → Webhooks** (push events).
+
+Do not add `LEXAI_API_KEY` or any provider key to this Coolify app.
