+ * This is a sample program that uses mecanum drive with a gyro sensor to maintian
+ * rotation vectors in relation to the starting orientation of the robot (field-oriented controls).
+ *
+ * WARNING: While it may look like a good choice to use for your code if you're inexperienced,
+ * don't. Unless you know what you are doing, complex code will be much more difficult under
+ * this system. Use IterativeRobot or Command-Based instead if you're new.
