 ## Usage
-Press ZL + L + ZR + R on the GamePad to take a screenshot.
+Press a button combo (default is L + R + ZL + ZR) on the GamePad to take a screenshot.
 
 Via the plugin config menu (press L, DPAD Down and Minus on the GamePad, Pro Controller or Classic Controller) you can configure the plugin. The available options are the following:
 - **Settings**: 
   - Enabled: (Default is true)
     - Enables or disables the screenshot plugin.
+  - Button combo: (Default is L + R + ZL + ZR)
+    - Changes the button combo for taking screenshots.
