 The foundational elements needed to get a specific keyboard working with ZMK can be broken down into:
 
 - A [KSCAN driver](https://docs.zephyrproject.org/2.3.0/reference/peripherals/kscan.html), which uses `compatible="zmk,kscan-gpio-matrix"` for GPIO matrix based keyboards, or uses `compatible="zmk,kscan-gpio-direct"` for small direct wires.
-- An optional matrix transform, which defines how the KSCAN row/column events are translated into logical "key positions". This is required for non-rectangular keyboards/matrixes, where the key positions don't naturally follow the row/columns from the GPIO matrix.

 - If you have a keyboard with options for `2u` keys in certain positions, or break away portions, it is a good idea to set the chosen `zmk,matrix_transform` to the default arrangement, and include _other_ possible matrix transform nodes in the devicetree that users can select in their user config by overriding the chosen node.
