GitHub is an awesome resource for developers. Besides providing a safe, secure, organized place to store the source code for your projects, it also has a way publish static files to the web. I use it for this site, and in this post, I'll show you how I set it up.

The first step is to create a github account and repository. GitHub has the best step-by-step instructions on how to do this. Go to their help site and follow the Setup Git and Create a Repo guides. Once you have a repository created and checked out on your local machine, you’ll use a feature called GitHub Pages to serve static files out to your users. This feature of GitHub will automatically publish anything checked into a specially named branch (gh-pages) to a url corresponding to your project name.

To create the GitHub pages branch, open a terminal and navigate to the root directory for your checked out project. Then type the following:

git branch gh-pages
git checkout gh-pages

The first command, “git branch gh-pages”, created a gh-pages branch. The second command, “git checkout gh-pages” switched your local, working source tree to that branch. Now, let’s open a text editor and create an index.html file in our new branch:

        <h1>Hello there from GitHub pages!</h1>

So far, so good. Now, we need to commit our changes and push them to GitHub so we can see them.

git add .
git commit
git push --set-upstream origin gh-pages

This set of commands first adds the new index.html file we created to git, the commits this revision, then pushes the changes up to GitHub.

Now, open a browser and check, where “username” is your GitHub username and “project” is the name of your project. If everything worked correctly, you should see the plain index.html we just created with a title of “Howdy” and a headline saying “Hello there from GitHub pages!”. If you have problems, wait a few minutes and check again (it can sometimes take a little time for GitHub’s publishing scripts to do their work). Also, be sure you named your branch exactly “gh-pages”. This is the special branch GitHub Pages is looking for. If you’re still having problems, check out the GitHub Pages Help.

Ok, the next step is to point your custom domain name at the url we just used. I manage my domain names through NameCheap. Your provider may be different, but the process should be similar. Go to the management page for your domain name and look for an option called “URL Forwarding”. Here you’ll want to create two CNAME entries, one for when someone enters and another one for when someone enters Here’s a screenshot of my entries for

CNAME Entries

The final piece of this puzzle is to create a CNAME file next to index.html (in the root of your project). This file should be named “CNAME” (all caps, with no extension) and contain your domain name (without the preceding http:// or www). For example, my CNAME file for this site looks like:

After committing and pushing the CNAME file, you should be able to access your site at and see the index.html in your gh-pages branch. The source code for this site is on GitHub, so you can always refer to it for reference and see how my code is setup. My master branch, containing the raw source code and build files, is at and the built version of that code (what you’re looking at now) is available in the gh-pages branch at
