I AM GROOT.
HOW TO ENABLE:
• Go into device settings
• Go to Language and Input Methods (or something along those lines, depending on phone manufacturer)
• Make sure the "GrootBoard" checkbox is checked (While keeping whatever is already checked checked)
• A scary dialog will pop up, but the app doesn't have internet access so it's not like I can send myself all of your Groots, even if I wanted to.
• From here it's enabled, and you can either set it as default if that's your thing, or choose it from the input method chooser which now shows up whenever you have a keyboard up.
• Groot away. I AM GROOT.
