+## Installation
+
+1. Install the original stock YouTube app.  
+   *Make sure you have the correct version installed before proceeding.*
+1. Install the module and wait for it to patch the YouTube app.  
+   *This might take a while.*
+   *Please refrain from doing anything else on your device in the meantime.*
+1. Go into the Google Play Store and disable automatic app updates for YouTube.
+1. Reboot
+
+## Concept
+
+In most legislations it is illegal to redistribute modified software 
+without consent of the copyright holder.
+
+For example:  
+The Windows modding community isn't allowed to distribute modified Windows ISOs
+but is allowed to distribute a patcher, 
+which the user can download to patch their geniune Windows ISO.
+
+The same concept can be applied to ReVanced.  
+Redistributing magisk modules with the patched YouTube APK is not legal.
+But we are totally fine distributing the patcher 
+and letting the user patch the original APK on his own.
+
+This module automates exactly this.
+You, the user, download the original YouTube APK yourself.
+This module will patch the installed YouTube APK during installation
+**right on your device**.
