 * teleop_joy.launch: Spawns a joy and teleop_twist_joy instance and remaps *cmd_vel* topics to */stretch_diff_drive_controller/cmd_vel*, which the robot is taking drive commands from. Note that the *teleop_twist_joy* package has a deadman switch by default which disables the drive commands to be published unless it is being pressed. For an Logitech F310 joystick this button is A.
 
 The *script* directory contains a single python file that publishes ground truth odometry of the robot from Gazebo.

+
+*Notes:* Although there is no microphone in Gazebo, Respeaker can be represented with a ROS node that accesses compputer's microphone. Cliff sensors are not modeled but they can also be represented as 1D LIDAR sensors. See LIDAR definition in *stretch_gazebo.urdf.xacro* file.
+
+## Gazebo - Moveit Controllers vs stretch_core
+
+Actuators are defined as *ros_control* transmission objects in Gazebo using [PositionJointInterfaces](http://docs.ros.org/en/melodic/api/hardware_interface/html/c++/classhardware__interface_1_1PositionJointInterface.html). Moveit is configured to use three different action servers to control the body parts of stretch in Gazebo through the srdf file in *stretch_moveit_config* package. See the section below about moveit for details. Please note that this behaviour is different than *stretch_core* as it works with a single Python interface to control all the joints.
+
 ## Setup
 
-Use `rosdep` to install the required packages.
+Clone stretch_ros and realsense_gazebo_plugin packages to your catkin workspace. Then install dependencies and build the packages, with the following set of commands:
+
+```bash
+    cd $CATKIN_WS/src
+    git clone https://github.com/hello-robot/stretch_ros
+    git clone https://github.com/pal-robotics/realsense_gazebo_plugin
+    rosdep install -r --from-paths . --ignore-src --rosdistro melodic -y
+    cd $CATKIN_WS
+    catkin build
+```
