+### Developing the UI
+
+To enjoy the live-reloading that `grunt dev` offers while working on the `metamask-ui` dependency:
+
+ 1. Clone the `metamask-ui` dependency locally.
+ 2. `npm install` in its folder.
+ 3. Run `npm link` in its folder.
+ 4. Run `npm link metamask-ui` in this project folder.
+ 5. Next time you `grunt dev` it will watch the metamask-ui for changes as well!
