Hello,

We are following the [Sentinel Quick Start Guide](https://docs.modalai.com/sentinel-quickstart/) for the Sentinel drone to bind a controller and connect to QGroundControl.  The video in the quick start guide states that the following services are required to be running: voxl-mavlink-server, voxl-px4, and voxl-vision-px4.  On our Sentinel drone the voxl-vision-px4 is not installed or running.  How do we get the voxl-vision-px4 service installed on the Sentinel drone?

Below is a list of the services that are running on our Sentinel drone.

@jarthur That video is quite outdated at this point, I would check out https://docs.modalai.com/voxl-developer-bootcamp/ for the most up to date info
