This guide is based on the originally posted article at Schmurfy's blog - I've modified it for current github pages flow.

Let's get it started.

First, clone Your nanoc page repository to local disk and enter it:

git clone yourRepoCloneUrl
cd yourRepoFolder

Now, if You don't have output folder yet create it, then clone Your repo again into that directory:

mkdir output
git clone yourRepoCloneUrl output

Let's enter this folder and create isolated (orphan) branch, gh-pages:

cd output
git checkout --orphan gh-pages

Next we have to clean all the contents from our output folder's git track:

rm -rf .

Now re-check if You are on gh-pages branch - there's possibility that You're now on detached state - if so then type:

git checkout gh-pages

To avoid problems in the future, remove the master branch binding from the output folder:

git branch -d master

Everything should be set here, so now enter the main project folder and try to compile it:

cd ..
nanoc aco

And that's it! Everything that is outside the output folder belongs to Your master branch (so You should push every change You want to keep.

If You want to publicize Your nanoc page, compile the project, enter the output folder (you should be switched automatically to gh-pages branch) then commit and push Your changes to Your gh-pages repo branch.

And that's it! If You ever need any help with nanoc and gh-pages - just let me know.
