You just need a gh-pages branch on the repo. The separate repo is only for the "root folder" of that subdomain (i.e. the content of the master branch of the repo pakastin/pakastin.github.io shows up at pakastin.github.io/ and the content of the gh-pages branch of the repo pakastin/xyz shows up at pakastin.github.io/xyz).

Thanks. I've been manually copying the directories into my gh-pages repo. lol.

Put some HTML code on the gh-pages branch :)
