-# Adding `digitalio` support to other ports
+# Adding ``*io`` support to other ports
 `digitalio` provides a well-defined, cross-port hardware abstraction layer built to support different devices and their drivers. It's backed by the Common HAL, a C api suitable for supporting different hardware in a similar manner. By sharing this C api, developers can support new hardware easily and cross-port functionality to the new hardware.
 
 These instructions also apply to `analogio`, `busio`, `pulseio` and `touchio`. Most drivers depend on `analogio`, `digitalio` and `busio` so start with those.
