 ##### step( *steps*, *direction*, *style* )
 
+If you want to move the stepper motor a set number of steps then you can use this command. This, however, will stop all processing until the motor has moved the specified number of steps.
+
+``` python
+stepper1.step(200, dw_Controller.FORWARD, dw_Controller.SINGLE)
+stepper1.step(200, dw_Controller.REVERSE, dw_Controller.DOUBLE)
+```
+
+If you want more control and need to move two or more motors at the same time then you should use the **oneStep** command.
