Templates
From Georgia Tech Student Wiki
Templates are a powerful tool to add information to new course, major, or other pages. This should simplify and standardize the ability for editors to compile information on any topic.
To create a template, make a new page with the following syntax:
Template:foo
This template can then be used using the following syntax. Note: if this format is used, any updates to the template will be shown on pages it is used within.
This could be useful for adding major requirements to pages.
To use that template and edit boilerplate text, use the following syntax:
{{subst:foo}}
This could be useful for creating new major or course pages.
