UNfortunately I was as lost as well when I started a few weeks ago. There is lots and lots of info and posts but it’s quite challenging to pick something that obv works ans stick to it.
What i did was get a cheap pump off aliexpress and a compression hanger. I’ve been doing that daily while learning about those two things and seeing how I can improve. Then with time I will see what to do else.
You can start with manuals, there is a guide on the landing page
