 ## Deploying
 
 There are 2 endpoints that the Web UI uses to 1) populate its UI, and 2) generate projects:
+
 * `/api/config/projectMetadata`
 * `/api/project`
- 
+
 For local development, these endpoints are implemented in the development webpack configuration in [start-client/webpack.dev.js](start-client/webpack.dev.js).
 
 In a remote deployment, those endpoints are implemented by the [Initializr API](https://github.com/SteeltoeOSS/InitializrApi).
