+# ESP32 Touch Brightness Control
+
+Toggle On/Off with a long press (800ms)
+Switch through 5 brightness levels (defined in usermod_touchbrightness.h, values 0-255) with a short (100ms) touch
+
+## Installation 
+
+Copy 'usermod_touchbrightness.h' to the wled00 directory.  
+in 'usermod_list.cpp' add this:
+
+> #include "usermod_touchbrightness.h"
+above "void registerUsermods()"
+
+and
+
+> usermods.add(new TouchBrightnessControl());
+inside the "registerUsermods()" function
