A template is a form that is displayed when an author creates a page. It can contain predefined content, and can also prompt the author to enter content in particular fields. You can make a template available across your entire Confluence site or just in a particular space. For example, a human resources space might have a template called 'Leave Request', or an information technology space might have a template called 'Asset Configuration'.
In addition to templates, Confluence comes with some predefined 'blueprints'. A blueprint is a template with added functionality to help you create and manage content in Confluence more efficiently. Think of a blueprint as a best practice guide, out of the box.
