To get a better understanding of Skyline here's a quick overview of the main building blocks.
Skyline is primarily built around pages. Pages are ordered into a tree which represents the structure of the website. Pages consist of two parts: static data and sections and they inherit their properties from articles.
Article is a container class that adds the functionality needed to add sections, versioning, publication
and other cool stuff. Pages are articles too. You can subclass the Article class to create your
own custom editable object (A news item for instance)
Sections are elements that are predefined and are used as building blocks for content. Skyline has a number of sections built in but you can also add new sections.
Skyline articles are rendered by the show action of the Skyline::Site::PagesController this controller can be overwritten if for instance you need to render a specific page template for an element that is not directly linked to a page. Like articles.
Settings can be used to link articles to pages but also to set defaults like templates or colors which then can be used in the templates.
