Creating a page with Go-Static! is just as simple Creating a post. Like creating a post, there are a couple ways to do it: either let the built in Yeoman generator scaffold out a new page for you, or you can just create a new file yourself in your favorite editor.
If you're using Go-Static! for the first time, this is a good way to go. Just run the generator for creating posts and follow the prompts.
$ yo go-static:page
The generator creates a new file (currently the default uses Markdown).
The file will contain "front matter" section at the top. This is a way to store all the meta details about the page. You can read more about Go-Static! front matter in the documentation.
For instance, the typical front matter for a page looks like:
layout: page title: About Us path: /about.html type: page created: '2013-09-20T19:28:35-07:00'
The generator creates this for you. Add your content below that section.
As you can see, Go-Static isn't magic. It simply uses Yeoman to automate the creation of posts, a step that can easily be done manually by you. Just create a new file with some meta details about the page, then run your build.
