What's a template, you may ask?
A template is a file that we can re-use to present different information in a consistent format – for example, you could use a template to help you write a letter because although each letter might contain a different message and be addressed to a different person, they will share the same format.
A Django template's format is described in a language called HTML (that's the HTML we mentioned in the first chapter, How the Internet works).
