Github pages for Github project

Question

I am new to Github pages. I followed their instructions for User, Organization, and Project Pages and Creating Project Pages manually , so I have something up at oresoftware.github.io , which is my Github "user site".

Now I am looking to put something up at oresoftware.github.io/suman, a "project site".

The problem, and this might be telling, is that

oresoftware.github.io/suman/index.html is available

but I get a 404 when going to

oresoftware.github.io/suman

there is probably a good reason for that, but I am not that knowledgeable with the www.

Why would this be? The project structure for my github repo (gh-pages branch) might give info about why - https://github.com/ORESoftware/suman/tree/gh-pages

Answer 1

As of today's date, your repo https://github.com/ORESoftware/suman has no gh-pages branch

a gh-pages branch is required for Github Pages
