	echo.

	echo 					system-images\android-^$API\google_apis_playstore\x86_64\
	echo.
	echo 	ANDROID_HOME:			By default, the script uses %%LOCALAPPDATA%%, to set its Android Home
	echo 					directory, search for AVD system-images and ADB binarys. This behaviour
	echo 					can be overwritten by setting the ANDROID_HOME variable.
	echo 					e.g. set ANDROID_HOME=%%USERPROFILE%%\Downloads\sdk
	echo.
	echo 	^$API:				25,29,30,31,32,33,34,UpsideDownCake,etc.
	echo.
	echo Options:
	echo 	restore				restore all existing .backup files, but doesn't delete them
	echo 					- the AVD doesn't need to be running
	echo 					- no other Argument after will be processed
	echo.
	echo 	InstallKernelModules		install custom build kernel and its modules into ramdisk.img
	echo 					- kernel (bzImage) and its modules (initramfs.img) are inside rootAVD
	echo 					- both files will be deleted after installation
	echo.
	echo 	InstallPrebuiltKernelModules	download and install an AOSP prebuilt kernel and its modules into ramdisk.img
	echo 					- similar to InstallKernelModules, but the AVD needs to be online
	echo.
	echo Options are exclusive, only one at the time will be processed.
	echo.
	echo Extra Arguments:
	echo 	DEBUG				Debugging Mode, prevents rootAVD to pull back any patched file
	echo.
	echo 	PATCHFSTAB			fstab.ranchu will get patched to automount Block Devices like /dev/block/sda1
	echo 					- other entries can be added in the script as well
	echo 					- a custom build Kernel might be necessary
	echo.
	echo 	GetUSBHPmodZ			The USB HOST Permissions Module Zip will be downloaded into /sdcard/Download
	echo.
	echo 	FAKEBOOTIMG			Creates a fake Boot.img file that can directly be patched from the Magisk APP
	echo 					- Magisk will be launched to patch the fake Boot.img within 60s
	echo 					- the fake Boot.img will be placed under /sdcard/Download/fakeboot.img
	echo.
	echo Extra Arguments can be combined, there is no particular order.
	echo.
	echo Notes: rootAVD will
	echo - always create .backup files of ramdisk*.img and kernel-ranchu
	echo - replace both when done patching
	echo - show a Menu, to choose the Magisk Version (Stable ^|^| Canary ^|^| Alpha), if the AVD is online
	echo - make the choosen Magisk Version to its local
