That yellow dot is showing your next objective, Pressing tab opens up a different menu, Tutorials are accessed from there, They are shown on screen briefly but its in a box to the top left of the screen and I can see how someone would miss them, The games not much for hand holding and leaves much to you to discover and sandbox through, It's not a game you can leeroy your way through though, Your gonna want to go slow and strategic, Use the enviroment to help or the game will hand you your butt repeatedly lol
