 ## Configuration
-AuthU is configured using the `OAuth.ConfigureEndpoint` helper inside an Umbraco `ApplicationEventHandler` like so:
-````csharp 
-    public class Boostrap : ApplicationEventHandler
+In order to configure AuthU you will first of all need to create an Umbraco composer + compontent combination like so:
+````csharp
+    public class AuthUConfigComponent : IComponent
     {
-        protected override void ApplicationStarted(UmbracoApplicationBase app, ApplicationContext ctx)
+        public void Initialize()
         {
-            OAuth.ConfigureEndpoint(...);
+            // Configuration goes here
         }

+    public class AuthUConfigComposer : ComponentComposer<AuthUConfigComponent>
+    { }
