# Overview

> Learn how to use the Liquid templating engine in Rootly workflows to dynamically manipulate data, format content, and create powerful automation expressions.

Rootly supports the use of the [Liquid](https://shopify.github.io/liquid/ "Liquid") templating engine in Workflows Tasks. Liquid provides a number of useful filters which can be used to manipulate the contents of options blocks. For example, the expression `{{ 'hello' | upcase }}` uses the upcase filter, when inserted into an options block it will render HELLO. You can string multiple Liquid filters together, with the expression processed left-to-right.
