-This a proof-of-concept Linux userspace driver to hardware-enable/-disable the touchpads on TongFang/Uniwill laptops. This will also trigger the disabled-led, formerly unfunctional under linux.
+# About
+This a Linux userspace driver to enable and disable the touchpads on TongFang/Uniwill laptops using a HID command. **This will trigger the touchpad-disabled-LED, formerly unfunctional under linux.**
 
-It syncs up with the software toggle in the gnome settings deamon.
+Most desktop environments already have a way to disable the touchpad, but this setting never reaches the firmware of the device. This driver listens to the session D-Bus and dispatches the approprita HID call to /dev/hidraw* whenever the setting changes, closing the gap to the device itself, and enabling the built in LED.
 
-It comes with some known disfuctionalities:
-- only works on desktop evnironments using gsettings/gio
-- does not work on loginscreen(gdm)
-- needs to be started for every user seperatly
-- every user needs write access to the /dev/hidraw* device for the touchpad (udev *.rules included)
-- switching between 2 users is not detected (on next toggle the software and hardware disable will be in sync again however)
+Currently this driver was only tested and works on the GDM greeter, GNOME Shell, Budgie, and KDE Plasmashell. All other environments, including the tty-console, work as before, meaning touchpad is always enabled on the HID level.

+
+There is also a target `make package` which is fine for testing, but it will not create a debian best practices compliant .deb. For this you need to use `gbp buildpackage` as described below.
+
+## Packaging
 ```
+$ sudo apt install libudev-dev libglib2.0-dev git-buildpackage
+$ gbp buildpackage -uc -us
+```
+A .deb package is created in the folder above the git repository.
+
+# Installing
+
+After installing via `make install` or using the .deb you need to reboot your system for the driver to load.
