+## What does it do ?
+
 This package provides an HTTP Interceptor, and a spinner component. The HTTP interceptor listens to all HTTP requests
 and shows a spinner during pending requests.
 
+## Usage
+
 In order to have this module listening to your http requests, replace all your ``http`` uses by [http: HttpInterceptorService](src/app/http-interceptor.service.ts).
 
+## Requirements
+
 It's compatible with Angular 4+.
 
+## Credits
+
 The spinner has been taken from [SpinKit](https://github.com/tobiasahlin/SpinKit).
