+brightness, colour levels, and input sources.  Generally speaking, any setting
+that can be changed by pressing buttons on the monitor can be modified by
+ddcutil.
+
+ddcutil communicates directly with monitors implementing the Monitor Control
+Command Set (@dfn{MCCS}).  It usually does so through the the Display Data
+Channel Command Interface (@dfn{DDC/CI}) protocol on the I2C bus, but can also
+communicate over USB as per the USB Monitor Control Class Specification.
+
+One particular use case is in colour profile management.  Monitor calibration
+is relative to the monitor colour settings currently in effect, e.g. red gain.
+ddcutil allows colour-related settings to be saved at the time a monitor is
+calibrated, and restored when the calibration is applied.")
