Most of what will be public on your website comes from template files that are defined in SilverStripe. Either in the
core framework, the modules or themes you install, and your own custom templates. 

SilverStripe templates are simple text files that have an `.ss` extension. They can contain any markup language (e.g HTML, 
XML, JSON..) and are processed to add features such as `$Var` to output variables and logic controls like 
`<% if $Var %>`. In this guide we'll look at the syntax of the custom template engine [SSViewer](api:SilverStripe\View\SSViewer) and how to render
templates from your controllers.
