 ## API
 
 There are two endpoints. The primary GraphQL endpoint is on `/api/graphql`. And the upload endpoint for the plugin is in `/api/update`.
 
 ## Developing
 
+The Module Federation Dashboard is a [NextJS application](https://nextjs.org/) that runs it's own GraphQL endpoint to serve data to the frontend code.
+
+Install the dependencies.

 ```bash
 yarn
 ```
 
+Start up the development server.
