CI with Travis, GitHub Releases API and gh-pages

When hosting a project on GitHub, it's likely you'll want to use GitHub Pages to host a public web site with examples, instructions, etc. If you're not using a continuous integration service like Travis, keeping your gh-pages site up to date requires continuous wrangling.

The steps below outline how to use Travis CI with GitHub Releases and GitHub Pages to create a "1-button" deployment workflow. After testing and running a release build, Travis will upload your release assets to GitHub. It will also push a new version of your public facing site to GitHub Pages.

Organize your project

Let's assume you are hosting a JavaScript project that will offer a single JavaScript file as a release asset. It's likely you'll organize your files like this.
