Casey Big Top Vape

I work on a website for my boss for her other business. I have no experience with computers, I really like using Microsoft Paint, I'm not joking about that. I don't know what codes are so please explain everything very simply! We're really just a small business trying to make ourselves a website, I don't work for a tech service or anything (obviously lol), just a cashier going to college. I think I'm really just going to be asking questions, don't really have any knowledge to give unless you need to know something about a cow or horse. Then I could help.
