I put the name of my repository as fingerstylebrasil.github.io but when I access it it appears that the page does not exist, I looked in the repository settings and another address appears here: link , that I can access the site normally, but it is not as it should, the correct one would be to get fingerstylebrasil.github.io named the repository name)
I want to know how to make the site url stay github.io
It is not possible for you to use the github.io domain, the repository name must be the same as the username or the organization name, otherwise GitHub will not "upará" your site .
As described on the User, Organization, and Project Pages page from GitHub Help
You can only use your own account name for a User or Organization Page repository. A repository like joe / bob.github.io will not build a User Pages site.
That is, it would work if your username was fingerstylebrasil or if your repository was called fmm312.github.io
Repositories are always considered as folders when they do not follow this pattern.
