### Technical
- Astro + Tailwind static site
- Configured for Railway or Cloudflare Pages deployment
- Interactive code examples with typewriter animation
- OS-specific install commands and download buttons

## Test plan
- [ ] `cd website && npm install && npm run build` succeeds
- [ ] `npx serve dist -s` serves the site locally
- [ ] Download buttons link to correct R2 URLs per platform
- [ ] Python SDK code examples are accurate and match current API
- [ ] C++ framework code examples are accurate
- [ ] All doc links point to amd-gaia.ai
- [ ] Deployment builds and serves correctly

+## Deployment
+
+### Railway (Recommended for Quick Deploy)
+
+See **[RAILWAY_DEPLOY.md](./RAILWAY_DEPLOY.md)** for detailed instructions.
+
+**Quick setup:**
+1. Push code to `github.com/amd/gaia-website`
+2. Connect Railway to your GitHub repo
+3. Railway auto-detects Astro and deploys
+4. Set custom domain to `amd-gaia.ai`
+
+**Auto-deploy:** Push to GitHub → Railway builds and deploys automatically
+
+### Cloudflare Pages (Recommended for Production)
+
+1. Connect your repository to Cloudflare Pages
+2. Set build command: `npm run build`
+3. Set output directory: `dist`
+4. Deploy
+
+**Benefits:** Faster global CDN, unlimited bandwidth, better DDoS protection
+
+### Manual Deploy
+
+```bash
+npm run build
+# Upload contents of dist/ to your hosting provider
+```
+
+## Assets Needed
+
+Before launch, add these assets to `public/`:
+
+- [ ] `og-image.png` (1200x630) - Social share image
+- [ ] Integration logos (VS Code, Blender, Jira, Docker)
+- [ ] GAIA logo SVG (if different from favicon)
