 What to know:
 
 * Please make sure you're running at least F-Droid 0.103
-* Reqiures Magisk 17+
-* If running Android 11+, I suggest using [Aurora Droid](https://f-droid.org/en/packages/com.aurora.adroid/) and [Aurora Services](https://github.com/whyorean/AuroraServices). F-Droid does not seem interested in updating their installer extension, and I will of course update this module when F-Droid updates their extension. 
+* Requires Magisk 20.4+
+* Use _Code_ > _Download ZIP_ from [the GitHub repo](https://github.com/Magisk-Modules-Repo/Fdroid-Priv) for the latest version of this installer
