17 years old 6'2 and some change 145 lb

I've been incredibly lanky since I was in elementary school and I've been putting off lifting because I feel like it won't work the same for me as it will for other people or there are things that I have to do differently that I can't do right now due to lack of resources. I have a really good build the V shape, broad shoulders is all there the only problem is I'm just very slim and need to gain muscle mass

First question: Do I have to do anything differently? Second question: Do I need to incorporate supplements when I start lifting?
