Are "how do I begin with XYZ" questions on topic here?
They have appeared before, but I'm not sure they're really suitable.
I find answers to such questions valuable for my own reading provided the person answering lists at least one reference I can go to for more information and explains why those references are relevant.
It is not always clear what one should be reading first to understand a new topic. It is also easy to give up in frustration. Hopefully a good answer helps avoid that frustration for someone.
I think such questions are on-topic and I would not vote to close them.
