While keyboards usually ship with a keymap programmed in, to be able to change that keymap, without flashing new firmware, we need a way to place the keymap into a place we can update at run-time, and which persists across reboots. Fortunately, we have a bit of `EEPROM` on the keyboard, and can use it to store either the full keymap (and saving space in the firmware then), or store additional layers there.
In short, this plugin allows us to change our keymaps, without having to compile and flash new firmware. It does so through the use of the [FocusSerial][plugin:focusSerial] plugin.
