 ## Description
-ConfigureAll is a library to make using the Options configuration pattern easier. Just implement IConfigurationObject and ConfigureAll!
+ConfigureAll is a library to make using the Options configuration pattern easier. Just add the ConfigurationObject attribute and ConfigureAll!
 
 ## How to use it
 
-1. Implement the IConfigurationObject interface on your configuration objects by adding a ConfigurationKey property indicating the name of the key in your configuration that maps to this object
+1. Add the ConfigurationObject attribute on your configuration objects indicating the name of the key in your configuration that maps to the object
     ```C#
     using SapientGuardian.ConfigureAll;
 
 
     namespace ConfigureAllTests
     {
+        [ConfigurationObject("TestKey")]
         public class TestConfigurationObject : IConfigurationObject
