 Scripts for passing a single GPU from a Linux host to a Windows VM and back.
 
-1. Change PCI ids in the vfio-startup and teardown script.
-2. Change the VM name in qemu if not already win10
-3. Run the install.sh script as root
+1. Change the VM name in qemu if not already win10
+2. Run the install_hooks.sh script as root
+
+Note the PCI ids and display manager should be detected automatically. If you are using an unsupported display manager that is not listed in the hooks/vfio-startup.sh script, feel free to contact us on the Discord server and we shall add your display manager.
+
+If using startx, add a line `killall -u user_name` to qemu/vfio-startup.sh script towards the beginning and you can add a line to vfio-teardown.sh to start your window manager/ desktop environment again. Don't just add startx because it will be run as root. Instead add `su -s /bin/bash -c "/usr/bin/startx" -g username username` replacing username with your username to the end of the vfio-teardown.sh script.
