+This edition of **Luma3DS** allows the loading of **.3GX plugins** in Luma3DS, which are otherwise officially unsupported.  
+  
+**Warning!** This was a quick, unstable hotfix I published to get things to work while waiting for official updates. The official firmware has now been updated to include 3gx plugins too. Do NOT use this fork.  
+  
 #
 ### How to install this Edition
 1. download the latest `boot.firm` from [the releases page](https://github.com/mind-overflow/Luma3DS-3GX/releases/latest)
