If your device is somewhere in the list, you got nothing to worry about. If not, you still got nothing to worry about, but make a backup before flashing!
As mentioned, installation of the keyboard is done by flashing a keyboard ZIP. Wipe cache + dalvik, flash the keyboard and wipe again. Easy, peasy. Enjoy your keyboard!
