How to Create GitHub Pages from Scratch?

[nerbivol]

Hello everyone,

I am new to GitHub Pages and I would like to create a GitHub Pages site from scratch. Could someone guide me through the process? Here are some specific points I need help with:

1. Repository Setup: How do I set up a repository for GitHub Pages?
2. Branch Configuration: Which branch should I use for my GitHub Pages site (main, gh-pages, or any other)?
3. Custom Domain: How can I use a custom domain for my GitHub Pages site for example learnmath.io?

Any detailed steps, resources, or examples would be greatly appreciated. Thanks in advance for your help!
