 ## Key Facts
 
-- **Package manager**: bun (preferred) or pnpm. Uses `@jsr` registry for `@nostr/tools`
+- **Package manager**: npm. Peer dependency conflicts are tolerated via `legacy-peer-deps=true` in `.npmrc`
 - **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`
