I am also very new to this, but it isn’t that hard once you’ve stay up till 1:00 3 or 4 times. Everything I needed to know was here: https://forum.magicmirror.builders/topic/236/complete-setup-tutorial/6 @KirAsh4
The section you probably need is under “Installing MirrorMirror2” at the end.
I was able to do everything from the forum until I needed to change the weather settings. For that, I used file manager. It isn’t as hard as it may seem (even though to a newbie like me all of this stuff seems hard). After a long time just playing around with it I finally got the MagicMirror2 app set up with autostart, which has a tutorial at: https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror
I hope this helps. I know how it feels to have no clue of what to do.
