 ## Running the Demo on the JACO 2
 
 ### Additional Workspace Setup
 
 1) Build your workspace with `catkin build`
-2) Download the checkpoint by going into `src/pytorch_retinanet` and running `load_checkpoint.sh` (or train your own checkpoint)
-2) Do the same in `src/bite_selection_package`: run `load_checkpoint.sh` (or train your own checkpoint)
+2) Download the PRL checkpoint with `. src/pytorch_retinanet/load_checkpoint.sh` (or train your own checkpoint)
+2) Do the same in: `. src/bite_selection_package/load_checkpoint.sh` (or train your own checkpoint)
 3) Make sure your source `devel/setup.bash` in *every* terminal you use.
 
 ###
 
 1) Start `roscore`, `rviz`
 2) Turn on ADA
 3) Once the lights on the joystick go solid, home ADA by holding the orange button until the robot stops moving.
-4) `ssh nano` (you may need to add `nano` to your `.ssh/config`, this is the Jetson on the robot). Once there, set your ROS Master using `uselovelace`, `useweebo`, or `useweebowired` (or set your ROS_MASTER_URI manually), execute `./run_camera.sh` to start streaming RGBD data.
+4) `ssh nano` (you may need to add `nano` to your `.ssh/config`, this is the Nvidia Jetson Nano on the robot). Once there, set your ROS Master using `uselovelace`, `useweebo`, or `useweebowired` (or set your ROS_MASTER_URI manually), execute `./run_camera.sh` to start streaming RGBD data.
    * You may have to adjust the camera exposure, depending on the lighting condition. Either run `run_adjust_camera_daylight.sh` or `run_adjust_camera_all.sh` after running `run_camera.sh`. Check the image stream via rviz, by adding the image topic `/camera/color/image_raw/color`. If some area is too bright and look burnt or saturated, reduce the exposure.
 5) `roslaunch forque_sensor_hardware forque.launch` (Optionally add `forque_ip:=<IPv4>` if your Net-FT is on a non-default IP)
 6) `rosrun face_detection face_detection`
