Ascribe templates are written in the Liquid templating language. Liquid mixes standard HTML markup with special markup consisting of output (variables that are replaced in the final HTML) and tags (control structures that can be used for looping, branching, and other purposes). In addition, Liquid offers various filters that can be used to modify the final output.
If you're not familiar with Liquid, follow the links in the sidebar for more information. If you already know how Liquid works, you can learn about the specific templates and variables that Ascribe offers for customization.
