+Realtime web analytics with privacy and simplicity at its core.
 
 ## Installation
 
 Add `https://github.com/GroupeMINASTE/DigiAnalytics.git` to your Swift Package configuration (or using the Xcode menu: `File` > `Swift Packages` > `Add Package Dependency`)
 
+## Register your app
+
+Go to [https://digianalytics.fr/websites/new](https://digianalytics.fr/websites/new) to register your app.
+
+You need to choose a domain name or subdomain to associate your app with.
+In this example, we will use `https://app.example.com/` as website URL.
+
 ## Usage
 
+Before sending any request, set your app website URL:
+
+```swift
+DigiAnalytics.shared.baseURL = "https://app.example.com/"
+```
+
+Then, send requests where you want to get analytics (e.g. in a view controller `viewDidAppear(_:)`)
+
 ```swift
-// TODO
+DigiAnalytics.shared.send(path: "home") // Will appear on dashbord as `https://app.example.com/home`
 ```
