but I’m enfretando a problem, my page sk9g3.github.com only 404
displays the message, someone could tell me where I am going wrong,
noting that I am not able to do the steps "git submodule add git@github.com:
/ .github.io.git public Almost done: add the deploy.sh script to help

Windows 8 operating system
