+# The overrides file is a JSON file that contains a single object. The key of that object
+# is the reference of the part of override, and the value is the amount of degrees to
+# add to the part's rotation. For instance, to rotate U1 by 90 degrees, and Q1 by 180
+# degrees, put the following value in the overrides.json file:
+# { "U1": 90, "Q1": 180 }
