+# About
+Global hotkeys for X11 and all Wayland compositors by using linux device api. Keyboards are grabbed and only the non-hotkey keys are passed through to the system.
+The program accepts text commands as input. Run the program with the option `--virtual` to only grab virtual devices. This is useful when using keyboard input mapping software such as
+kanata, otherwise kanata may fail to launch or this program may fail to launch.
+# Commands
+## Bind
+To add a key send `bind <action> <keycode+keycode+...><newline>` to the programs stdin, for example:
+```
+bind show_hide 56+44
+
+```
+which will bind alt+z. When alt+z is pressed the program will output `show_hide` (and a newline) to stdout.
+The program only accepts one key for each keybind command but accepts a multiple modifier keys.
+The keybinding requires at least one modifier key (ctrl, alt, super or shift) and a key to be used.
+The keycodes are values from `<linux/input-event-codes.h>` linux api header (which is the same as X11 keycode value minus 8).
+## Unbind
+To unbind all keys send `unbind_all<newline>` to the programs stdin, for example:
+```
+unbind_all
+
+``` \ No newline at end of file
