+# Browser Extension (Manifest v3) Scaffold
+
+This folder contains the initial Manifest v3 scaffold for the Recipe Manager browser extension.
+
+## Files
+
+- `manifest.json` — extension manifest
+- `background.js` — service worker and context menu registration
+- `popup.html` / `popup.js` — basic action popup
+- `options.html` — placeholder settings page
+- `styles.css` — shared minimal styles
+
+## Load locally (Chrome)
+
+1. Open `chrome://extensions`
+2. Enable **Developer mode**
+3. Click **Load unpacked**
+4. Select this folder: `browser-extension/`
+
+Future tasks will wire the context menu action to the import API and implement settings persistence for base URL.
