How can I host my own website files after setting up with Superhi?

Hey everyone! I'm a beginner coder and I recently built my site using the Superhi editor. I've also purchased my own domain through a registrar and got everything up and running. Now I'm looking to take things a step further by using version control software (VCS) to edit and host my own files instead of relying solely on the Superhi editor. How can I achieve this with the domain I already have? Just a note, I initially bought the domain from iwantmyname and switched my DNS to Cloudflare. Thanks for any help!
