 ### Mocked backend
 
-To start the development mode, run `yarn start:dev:mock` .
 This task will run the frontend in mock-mode, meaning instead of running a real backend, the frontend mocks the backend.
 This way you can work on frontend functionality without starting up the full development environment.
+The downside of this method is that you can't save notes and that realtime collaboration features are not available.
+To start the development mode, run `yarn start:dev:mock`.
