-Inside the details of this step you will see how to use it. At the top is a summary for the very basic usage, but when scrolling down you go through the README of the step which will usually contain more details about how to use it including a full example of using the step. So we return to our project, and while making it fit our project better we add these details to our wercker.yml file so it looks like this. Wercker also has a [page](http://devcenter.wercker.com/articles/werckeryml/validate.html) for validating wercker.yml files, and it's usually a good idea to do so before committing changes.

+In order to deploy to GitHub Pages we need to add a deploy step. Once again searching through the Steps repository we find that the most popular step is the **lukevevier/gh-pages** step so we add the configuration for that to our wercker.yml file.
