+# Ability Extensions
+You have around 100 abilities in your bot and you're looking for a way to refactor that mess into more modular classes. `AbillityExtension` is here to support just that! It's not a secret that AbilityBot uses refactoring backstage to be able to construct all of your abilities and map them accordingly. However, AbilityBot searches initially for all methods that return an `AbilityExtension` type. Then, those extensions will be used to search for declared abilities. Here's an example.
+```java
+public class MrGoodGuy implements AbilityExtension {
+  public Ability () {
+    return Ability.builder()
+           .name("nice")
+           .privacy(PUBLIC)
+           .locality(ALL)
+           .action(ctx -> silent.send("You're awesome!", ctx.chatId())
+          );
+  }
+}
+
+public class MrBadGuy implements AbilityExtension {
+  public Ability () {
+    return Ability.builder()
+           .name("notnice")
+           .privacy(PUBLIC)
+           .locality(ALL)
+           .action(ctx -> silent.send("You're horrible!", ctx.chatId())
+          );
+  }
+ }
+ 
+ public class YourAwesomeBot implements AbilityBot {
+    
+    // Constructor for your bot
+  
+    public AbilityExtension goodGuy() {
+        return new MrGoodGuy();
+    }
+    
+    public AbilityExtension badGuy() {
+      return new MrBadGuy();
+    }
+    
+    // Override creatorId
+ }
+```
