web: How does Metronic work?

I would like to use the theme Metronic provides. However, even with its documentation, I don't get how I am supposed to use it as a front-end solution.

Could someone please give me some advice on building a user interface for a web application using the Metronic theme?

For example: How would I generate a profile page using this theme? (which should include different things than those given in their demos)
