    RFP overrides FPP (4000)
 
-   It is an all-or-nothing buy in: you cannot pick and choose what parts you want
+   FF128+ Arkenfox by default uses FPP (automatically enabled with ETP Strict). For most people
+   this is all you need. To use RFP instead, add RFP (4501) to your overrides, and optionally
+   add letterboxing (4504), spoof_english (4506), and webgl (4520).
