 At this point, ZMK is _missing_ more features than it has. Currently, the mostly working bits
 include:
 
-- HID Over GATT (HOG) - This is the official term for Bluetooth Low Energy HID devices.
+- HID Over GATT (HOG) - This is the official term for BLE HID devices.
 - Keymaps and layers with basic keycodes.
 - Some initial work on one "action", Mod-Tap.
 - Basic HID over USB - This somehow _conflicts_ with BLE at least on the stm32wb55rg dev kit, so investigation needed.
