I can see why you have bumped this thread as some newbies didn't do their research and instead waiting for someone to spoon feed them the details to learn faster. I think it should be included in op that doing your own research would also help learning much easier. For newbies to know, Ratimov has made a thread that contains a list of helpful, important threads through links ranging from 2018 to 2021. The list contains threads that will be useful later on.
