+This program requires LEGO® MINDSTORMS® EV3 MicroPython v2.0 downloadable at https://education.lego.com/en-us/support/mindstorms-ev3/python-for-ev3.
+
+Control RoboDoz3r as follows:
+
+- RoboDoz3r starts with the User-Controlled Mode. You can switch between the User-Controlled Mode and the Autonomous Mode by pressing the Touch Sensor.
+
+- User-Controlled Mode:
+
+    - Drive RoboDoz3r around according to instructions from Channel 1 of the IR Remote Control:
+        - 2 Top/Up Buttons together: drive forward
+        - 2 Bottom/Down Buttons together: drive backward
+        - Top-Left/Red-Up and Bottom-Right/Blue-Down together: turn left on the spot
+        - Top-Right/Blue-Up and Bottom-Left/Red-Down together: turn right on the spot
+        - Top-Left/Red-Up: turn left forward
+        - Top-Right/Blue-Up: turn right forward
+        - Bottom-Left/Red-Down: turn left backward
+        - Bottom-Right/Blue-Down: turn right backward
+
+    - Use Channel 4 of the IR Remote Control to make RoboDoz3r raise the shovel by pressing either Up button, or lower the shovel by pressing either Down button
+
+- Autonomous Mode: RoboDoz3r drives around on his own to clean up small things but avoids big obstacles by reversing and turning
