I read the manual and then I search the internet for any rule unclarity to se if there is an answer (errata, FAQ, community consensus). Almost never watch videos, don't learn from them as well as I do from reading. Usually read the rules if I'm going to introduce someone new to the game even if someone previously explained it live. Have had to many cases of someone teaching the rules wrong, to blindly trust someone (except like one other person I know who is usually correct about everything)
