+
+var manager = Configuration.NewInstance(applicationId, apiKey);
+
+//Start monitoring changes in your application settings and features toggles.
+manager.StartMonitor();
+
+//Access your application settings
+var color = manager.GetSetting("application.color");
+
+//Check if your feature toggles are enable
+var status = manager.IsFeatureEnabled("you.feature");
+
+```
+
+## Optional parameters

+Change your environments:
+
+```csharp
+var env = "PRODUCTION";
+var refreshInterval =  TimeSpan.FromSeconds(10);
