 This library allows using ShowMyHomework.co.uk API to retrieve assigned tasks.
 
+## Getting Started
+To start using `Ovicus.ShowMyHomework`, install the latest version from [Nuget](https://www.nuget.org/packages/Ovicus.ShowMyHomework/).
+
+`PM> Install-Package Ovicus.ShowMyHomework`
+
+To retrieve the pending tasks, create a new instance of `ShowMyHomeworkClient` and call the method `GetTodos()`.
+
+```csharp
+var client = new ShowMyHomeworkClient(accessToken);
+
+var todos = await client.GetTodos();
+
+foreach (var todo in todos)
+{
+   var subject = todo.Subject; 
+   var title = todo.Title;
+   var dueDate = todo.DueOn; 
+}
+```
+
+If you need to generate an access token, the library `Ovicus.ShowMyHomework.Auth` can help with this. Install the latest version from [Nuget](https://www.nuget.org/packages/Ovicus.ShowMyHomework.Auth/).
+
+`PM> Install-Package Ovicus.ShowMyHomework.Auth`
+
+```csharp
+var authService = new AuthenticationService();
+
+bool isAuthenticated = await authService.Authenticate(username, password, schoolId);
+
+if (isAuthenticated)
+{
+    var accessToken = await authService.GetAccessToken();
+    // Use the accessToken to create an instance of ShowMyHomeworkClient
+}
+```
+
+You must call the `Authenticate()` method with a valid `username`, `password` and `schoolId`.
