Camping in the wilderness

How to camp in the wilderness and how do you get there to even set up a camp? I want to get into wilderness camping and am not sure where to start. I am planning to go all in and get a tent, backpack, and other camping equipment. I even watched YouTube vids on it. Do I need a license to camp? How do I even find a place to camp in the wilderness? Do you have to know how to navigate or map read? I am planning to go out in a couple of weeks.
