 # Control Surface
 
-An Arduino library for MIDI controllers and control surfaces. 
-It includes a general-purpose MIDI abstraction layer as well, which can be useful
-for any MIDI-related project.  
-Control surfaces with both MIDI outputs (potentiometers, buttons, etc.) and
-MIDI inputs (LEDs, displays, etc.) are supported.
+Control Surface is an Arduino library for building MIDI controllers and control
+surfaces.
+At its core is a
+[general-purpose MIDI abstraction layer](https://tttapa.github.io/Control-Surface-doc/Doxygen/d3/df7/midi-tutorial.html)
+with support for serial MIDI, MIDI over USB, MIDI over BLE, etc., which can be
+useful for any MIDI-related project.  
+Besides MIDI input/output, Control Surface also includes easy-to-use utilities
+specifically for building MIDI controllers, supporting controls that send MIDI
+─ like potentiometers, push buttons, rotary encoders, etc. ─
+and controls that react to incoming MIDI ─ LEDs, displays, and so on.
+They can also be combined into controls that use both MIDI input and output, 
+such as motorized faders.
