Hi and welcome

Toby's vids are very comprehensive and a great guide to how to do the basics of bbq properly. Watch them

A common source of frustration for new smokers is the "stall", which occurs between 150 and 170 F. It can last *hours*, and can worry people that they are overcooking. It is a natural part of the process due to surface moisture evaporating and cooling the meat. As Joe says, wrapping the meat helps shorten the stall and keep meat moist. It also makes it easier to get off the grill than a pork shoulder that is falling to pieces!
I have even left wrapped pork butts to get up to 212 F before. So tender. You can't rush these things, the meat is done when it's done and not a moment before. For your first few smokes, it pays to have a backup that you can quickly rustle up!
If your oven is reliable, you can bring the meat inside once it's foiled as it won't take on any more smoke, but it's more fun to leave it in the smoker
