AI driver project

Hello everyone!
I am working on a project in my degree in which I train an agent in unity, using ML agents, to drive a car and complete routes optimally.
I would be happy if someone who knows about a good guide and updated one the explain how to use ML agents will share it with me, and in addition, I would like to know how to upload a Unity project with ML-agents to github - should I upload all the package with the project? or I can just gitignore it and the agents I train will save their learning data somewhere else in the project.
Thank you in advance to anyone who will help.
