We were all nobs at some point.
Get comfortable with yaml, it makes it so much easier, i do most things in VSCode plugin.
Then the best newbie advice that I never got, is split your config from the get go, it get very annoying if everything lands up in 1 or 2 files and you have to dig to find something.
There are many videos on the subject, and I found frenck’s config very helpful
