-### How To Use it
-* run rootAVD with a path to an AVDs ramdisk.img file
-* ramdisk.img gets a backup and will be replaced when done patching
-
-### How To Use it under Android S with Magisk v22.x
-* rootAVD needs to run twice
-* 1st - to patch the ramdisk.img
-* 2nd - after Shut-Down & Reboot the AVD:
-	* Option 1 - re-run same script command
-	* Option 2 - run script with EnvFixTask Argument
-		* The "Additional Setup Required" will not be triggered in Android S by Magisk App in AVD,
-		* this must be done manually on the 2nd run
-		* Grant Shell Su Permissions will pop up a few times
-		* rootAVD will reboot the AVD automatically
-		* check Magisk App !!

-## Download / Install / Update a custom (pre)build Kernel and its Modules
-### Preconditions
-* Install Magisk Preconditions
-* build a kernel (bzImage) and its modules (initramfs.img)
-* both files are placed inside the rootAVD directory
-* ramdisk.img must be untouched (stock)
-
-### How To Use it
-* run rootAVD with the additional **InstallKernelModules** | **InstallPrebuiltKernelModule** parameter
-* the modules inside ramdisk.img will be replaced by the modules inside initramfs.img
-* kernel-ranchu gets a backup and will be placed with bzImage when done patching
-* bzImage and initramfs.img will be deleted after installation
-
-### Notes
-* Prebuilt Kernel and Modules will be pulled from [AOSP](https://android.googlesource.com/kernel/prebuilts)

+rootAVD A Script to root AVD by NewBit XDA
 
-#### MacOS
-```
-export PATH=$PATH:~/Library/Android/sdk/platform-tools
+Usage:	rootAVD [DIR/ramdisk.img] [OPTIONS] | [EXTRA_CMDS]
+or:	rootAVD EnvFixTask
+
+Requires Additional Setup fix:
+	EnvFixTask			construct Magisk Environment manual
+					- only works with an already Magisk patched ramdisk.img
+					- without [DIR/ramdisk.img] [OPTIONS] [PATCHFSTAB]
+					- needed since Android 12 (S) rev.1
+					- Grant Shell Su Permissions will pop up a few times
+					- the AVD will reboot automatically
+	
+Main operation mode:
+	DIR				a path to an AVD system-image
+					- must always be the 1st Argument after rootAVD
+	
+ADB Path | Ramdisk DIR:
+	[M]ac/Darwin:			export PATH=~/Library/Android/sdk/platform-tools:$PATH
+					~/Library/Android/sdk/system-images/android-$API/google_apis_playstore/x86_64/
+	
+	[L]inux:			export PATH=~/Android/Sdk/platform-tools:$PATH
+					~/Android/Sdk/system-images/android-$API/google_apis_playstore/x86_64/
+	
+	[W]indows:			set PATH=%LOCALAPPDATA%\Android\Sdk\platform-tools;%PATH%
+					%LOCALAPPDATA%\Android\Sdk\system-images\android-$API\google_apis_playstore\x86_64\
+	
+	$API:				25,29,30,S,etc.
+	
+Except for EnvFixTask, ramdisk.img must be untouched (stock).
+	
+Options:
+	restore				restore all existing .backup files, but doesn't delete them
+					- the AVD doesn't need to be running
+					- no other Argument after will be processed
+	
+	InstallKernelModules		install custom build kernel and its modules into ramdisk.img
+					- kernel (bzImage) and its modules (initramfs.img) are inside rootAVD
+					- both files will be deleted after installation
+	
+	InstallPrebuiltKernelModules	download and install an AOSP prebuilt kernel and its modules into ramdisk.img
+					- similar to InstallKernelModules, but the AVD needs to be online
+	
+Options are exclusive, only one at the time will be processed.
+	
+Extra Commands:
+	DEBUG				Debugging Mode, prevents rootAVD to pull back any patched file
+	
+	PATCHFSTAB			fstab.ranchu will get patched to automount Block Devices like /dev/block/sda1
+					- other entries can be added in the script as well
+					- a custom build Kernel might be necessary
+	
+	GetUSBHPmodZ			The USB HOST Permissions Module Zip will be downloaded into /sdcard/Download
+	
+Extra Commands can be combined, there is no particular order.
+	
+Notes: rootAVD will
+- always create .backup files of ramdisk.img and kernel-ranchu
+- replace both when done patching
+- show a Menu, to choose the Magisk Version (Stable || Canary), if the AVD is online
+- make the choosen Magisk Version to its local
+- install all APKs placed in the Apps folder
