  * configuration. This default can be obtained with the respective
  * get_default call.
  *
+ * Configuration options are device dependent and not all options are
+ * supported on all devices. For all configuration options, libinput
+ * provides a call to check if a configuration option is available on a
+ * device (e.g. libinput_device_config_calibration_has_matrix())
+ *
  * Some configuration option may be dependent on or mutually exclusive with
  * with other options. The behavior in those cases is
  * implementation-dependent, the caller must ensure that the options are set
  * in the right order.
+ *
+ * Below is a general grouping of configuration options according to device
+ * type. Note that this is a guide only and not indicative of any specific
+ * device.
