Not to be funny, but, we have no idea where you are at knowledge wise. Do you have a design you want to implement? If you aren’t at that phase then there really isn’t a starting point for using the software yet.
I am new as well, and i have restarted my project once already, and i might do it again, i have found many useful guides on this website, but my file hierarchy for building projects, has caused me a lot of confusion… like yes, i want my own symbol library, yes, i want a footprint library, yes, i need somewhere for pdfs, yes, i made a folder for all these sub directories called gaylord, and then i start reading about envs and do i make the gaylord directory and env? and put it under my .pro project file? If not, where is the best information (preferably video) reguarding this information? I might have to restart my project because of this
