A Template is used to create a Page and defines which components can be used within the selected scope. A template is a hierarchy of nodes that has the same structure as the page to be created, but without any actual content.
Each Template will present you with a selection of components available for use.
Templates are built up of Components;
Components use, and allow access to, Widgets and these are used to render the Content.

A template is the basis of a page.
To create a page, the template must be copied (node-tree /apps/<myapp>/templates/<mytemplate>) to the corresponding position in the site-tree: this is what happens if a page is created using the Websites tab.
This copy action also gives the page its initial content (usually Top-Level Content only) and the property sling:resourceType, the path to the page component that is used to render the page (everything in the child node jcr:content).
There are two aspects to be considered:
- the structure of the template itself
- the structure of the content produced when a template is used
A Template has a node type of cq:Template.
Various properties can be set, in particular:
- jcr:title - title for the template; appears in the dialog when creating a page.
- jcr:description - description for the template; appears in the dialog when creating a page.
This node contains a jcr:content (cq:PageContent) node which be used as the basis for the content node of resulting pages; this references, using sling:resourceType, the component to be used for rendering the actual content of a new page.

Apps are represented as cq:Pages in AEM. They share the same common properties found in any cq:Page that represent integration supporting properties.
See Content Properties and Exporting Content for more details.
