+      <p>
+        Keyboards with onboard controllers are single PCBs that contain all the
+        components of a keyboard, including the controller chip, switch
+        footprints, etc.

+      <h3>Composite Boards</h3>
+      <p>
+        Composite keyboards are composed of two main PCBs: a small controller
+        board with exposed pads, and a larger keyboard PCB (a shield, in ZMK
+        lingo) with switch footprints and location a where the controller is
+        added.
