 ### Movement ###
 You can move with w,a,s,d. Holding SHIFT will make you move faster.
 Pressing SPACE will capture the mouse.
 You can look around with the mouse while it is captured.
 Pressing SPACE again releases the mouse.
 
 ### Additional tips ###
+Shadows are turned off by default to increase compatibility. However you can enable them by
+setting "ENABLE_SHADOWS" to 1 in the file "fragment.glsl".
+
 Feel free to play with fragment.glsl and vertex.glsl:
 The core of the raytracer is in fragment.glsl.
 However there are some properties that can be changed in vertex.glsl (eg camera field of view).
