+In order to start up the simulation:
+```
+roslaunch mybot_gazebo mybot_world.launch
+roslaunch roslaunch curio_viz view_model.launch
+```
+
+Send a base controller command and ensure that the robot moves in both Gazebo and rviz:
+```
+rostopic pub /cmd_vel geometry_msgs/Twist "linear:
+  x: 0.2
+  y: 0.0
+  z: 0.0
+angular:
+  x: 0.0
+  y: 0.0
+  z: 0.1"
+```
+
+To make a map:
+Terminal A: 
+A$: roslaunch curio_gazebo curio_shapes_world.launch 
+will start up gazebo and rqt_robot_steering
+Terminal B:
+B$: ± roslaunch curio_viz view_robot.launch 
+Terminal B:
+C$: ± rosrun gmapping slam_gmapping scan:=sensors/laser
+Gazebo:
+ Don't forget to hit 'play' before you move the robot around.
+
+Driver the robot around, making a map as seen in rviz.  When you are happy with the map:
+ rosrun map_server map_saver -f <map_name>
