# Converting to Liquid templates

## Overview

This article is for pre-2022 templates, built with our legacy HTML syntax: **use it if your tags are in `$tag;` format.**

In 2022, Opensense switched from HTML with unique Opensense tags and conditional clauses to Liquid syntax. Liquid is an open-source template language, used by Shopify.com, that adds tags and outputs to HTML. It gives you greater conditional capabilities in signatures.

If your signature templates were built with Opensense tags and clauses, you can switch to Liquid templates. Most customers won't feel an immediate need to switch. But if you have advanced conditional requirements for your employee email signatures, or you're more familiar with Liquid syntax, a switch might be right for your account.

## Liquid tags and outputs

<dl class="kb-insights-summary">
  <div><dt>Tags</dt><dd>A tag name and optional arguments, wrapped between <code>{%</code> and <code>%}</code>.</dd></div>
  <div><dt>Outputs</dt><dd>A value and optional filters, wrapped between <code>{{</code> and <code>}}</code>.</dd></div>
</dl>

For more information on Liquid syntax, see the [Liquid documentation](https://shopify.github.io/liquid/).
