Adding exoskeleton to a current model

[Mohamed Mohanna]

Hi
I am new to opensim and I have mainly interacted with its GUI.
Now I would like to add an exoskeleton joint on a specific joint in order to analyze the difference in the muscle activity and joint dynamics.
Could you guide me through the steps required to implement this? Additionally, if there are any useful resources or best practices for this process, I would greatly appreciate your recommendations.
thanks in advance
