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.

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.
