+
+```bash
+bun run dev              # Development: runs build.js + tailwindcss --watch
+bun run build            # Production build → extension/output
+bun run package:chrome   # Creates extension/releases/nostrconnect_chrome.zip
+bun run package:firefox  # Creates extension/releases/nostrconnect_firefox.xpi
+bun run lint             # Run Biome linter
+bun run format           # Format with Biome (auto-fix)
+bun run test             # Run tests with Vitest
+bun run test:watch       # Run tests in watch mode
+```
+
+## Key Facts
+
+- **Package manager**: bun (preferred) or pnpm. Uses `@jsr` registry for `@nostr/tools`
+- **Build output**: `extension/output/` (not `dist/`)
+- **Ignore `extension/output/`**: It contains generated JS/HTML/CSS and is gitignored
+- **Tailwind source**: `extension/style.css` → `extension/output/style.css`
+
+## Architecture
+
+| File                                     | Purpose                                                   |
+| ---------------------------------------- | --------------------------------------------------------- |
+| `background.js`                          | Core logic: state, permissions, crypto (signEvent, nip04) |
+| `nostr-provider.js`                      | Injected into web pages, provides `window.nostr`          |
+| `content-script.js`                      | Bridges provider ↔ background via postMessage             |
+| `popup.jsx`, `prompt.jsx`, `options.jsx` | React UI components                                       |
+| `extension/chrome/manifest.json`         | Chrome Manifest V3 config                                 |
+| `extension/firefox/manifest.json`        | Firefox Manifest V2 config                                |
+
+The build script (`build.js`) auto-selects the correct manifest based on `prod`/`firefox` args.
+
+## Code Style
+
+- No semicolons
+- Single quotes
+- Biome (configured in `biome.json`)
