If you're familiar with command-line Git, it's straightforward to manually create a Github Pages site.

Make a fresh clone

To set up a Project Github Pages site, you need to create a new "orphan" branch (a branch that has no common history with an existing branch) in your repository. The safest way to do this is to start with a fresh clone:

$ git clone github.com/user/repository.git# Clone our repositoryCloning into 'repository'...remote: Counting objects: 2791, done.remote: Compressing objects: 100% (1225/1225), done.remote: Total 2791 (delta 1722), reused 2513 (delta 1493)Receiving objects: 100% (2791/2791), 3.77 MiB | 969 KiB/s, done.Resolving deltas: 100% (1722/1722), done.

Create a gh-pages branch

1

Switch directories into your new cloned repository:

$ cd repository

2

Check if your repository already has a gh-pages branch:

$ git branch# shows a list of branches for your repository* branch-name* branch-name

3

If you don't already have a gh-pages branch in your repository, create a new gh-pages branch:

$ git checkout --orphan gh-pages# Creates a `gh-pages` branch, without any parents (it's an orphan!)Switched to a new branch 'gh-pages'

Remove all files to create an empty working directory

$ git rm -rf .# Remove all files from the old working treerm '.gitignore'

Add content and push

$ echo "My Page" > index.html$ git add index.html$ git commit -a -m "First pages commit"$ git push origin gh-pages

Load your new GitHub Pages site

After your push to the gh-pages branch, your Project Pages site will be available at 'http(s)://[username].github.io/[projectname]' . Note that Pages are always publicly accessible when published, even if their repository is private.
