I would recommend asking an expert to bootstrap you. That's the quickest solution often it's a trivial thing you just don't know and the time you need to grasp it may be better invested in doing something you're more qualified in. And a working condition is a better starting point unless you want to become the expert than it's bottom up and as a user it's top down.
To the problem question.
Progressive solution: Try to get a tutorial with a working basic setup and start changing 1 parameter at the time to get from initial state A to wanted state N. But always stay reversible. That way you always can return to a working state, which is less frustrating.
Immersive solution: Read the documentation first, -> start with reading only the index, move to cross-read the chapters, move to detail reading the chapters still ignore all examples only 'what is the point' not 'how do I get to the point', move to reading the configurations and examples. Test everything invest 2-3 Weeks into the technology do 10 different setups understand the differences.
Based on what you actually want to achieve I would pick a strategy, you can change it afterwards.... I don't know what you want to achieve.
