Create a public repo with the name: your_github_id.github.io. Example: if my GitHub ID is franciscovilchezv, my repo will be called franciscovilchezv.github.io.
Add a file index.html to the repo (make sure you include it in the root of the repo. In other words, it must NOT be inside any additional directory/folder)
Include the information you want in your index.html and save it in the repo.
Go to the repo and click on "Settings"
Got to the "Pages" tab.
Select branch main instead of None, and next to it the option / (root), then save.
Wait ~1 minute and then your website should be available at your_github_id.github.io
