Hi @torin-stephen and welcome to the GitHub Support Community! In order to make a GitHub Pages site at
https://torin-stephen.github.io, you’ll need to create a repository called
torin-stephen.github.io and enable GitHub Pages on it.
[username].github.io is the respository your personal GitHub Pages site is built from, and any project sites are located in directories under that domain (e.g.
/about in your example).
For more detailed information, please see creating a GitHub Pages site - that goes through more details about how user sites and project sites work.
