 Hoverfly UI is the Angular 4 frontend application that is bundled with [Hoverfly](https://github.com/SpectoLabs/hoverfly).
 
-## Getting started
+## Prerequisites
+The project is generated by [Angular CLI](https://github.com/angular/angular-cli) v1.1.0, which requires Node 6.9.0 or higher, and NPM 3 or higher.
+You also need [Hoverfly](https://github.com/SpectoLabs/hoverfly) v0.12.0 or higher which can enable developer mode.
 
-To develop this application, you will need to run Hoverfly in developer mode. This is to enable Cross Origin Resource Sharing headers, which will enable the Hoverfly UI to successfully communicate with Hoverfly across ports.
+## Getting started
