-- Umbraco HQ owns the Management API on the backend, so features can be worked on in the frontend only when there is an API, or otherwise if no API is required
-- A contribution should be made in a fork of the repository
-- Once a contribution is ready, a pull request should be made to this repository and HQ will assign a reviewer
-- A pull request should always indicate what part of a feature it tries to solve, i.e. does it close the targeted issue (if any) or does the developer expect Umbraco HQ to take over

 ## API mock handlers
 
 Running the app with `npm run dev`, you will quickly notice the API requests turn into 404 errors. To hit the API, we need to add a mock handler to define the endpoints that our dashboard will call. In the case of the Published Cache Status section, we have several calls to work through. Let’s start by looking at the call to retrieve the current status of the cache:
