# Adding comments to design templates (Liquid templates)

## Overview

This article uses the current Opensense template syntax, Liquid (**as of 2022**). If you're used to the older format, see [HTML and field types (legacy templates)](https://help.opensense.com/docs/html-field-types-1).

## Use cases

- Around unfinished code
- To explain how a signature operator works, so it's easy to find

Comments **aren't** displayed when emails are sent.

## Example

```liquid
{% comment %}
The operator below lets you display the address that matches the sender's location.
You can easily add new locations by creating a new {% when "" %} statement,
and saving the signature template.
{% endcomment %}

{% case location %}

{% when "New Jersey" %}
555 Highpoint Lane<br />
Englewood, NJ 07631

{% when "Atlanta" %}
1234 Pleasant Street<br />
Atlanta, GA 30301

{% else %}
1234 HQ Lane<br />
Louisville, KY 40210
{% endcase %}
```


<div class="kb-media-carousel" data-kb-media-carousel aria-label="A comment in a template">
  <div class="kb-media-carousel__viewport">
    <figure class="kb-media-frame"><div class="kb-media-frame__visual"><img src="https://help.opensense.com/media/addcomments1-75fc18352d05.png" alt="The HTML Template editor, where a comment block explains the case statement on location below it" width="991" height="462" loading="lazy" decoding="async"></div><figcaption><strong>HTML code</strong> · The comment above the case statement</figcaption></figure>
    <figure class="kb-media-frame"><div class="kb-media-frame__visual"><img src="https://help.opensense.com/media/addcomments2-8d3a81b8a490.png" alt="A rendered signature with the Atlanta address; the template comment doesn't appear" width="616" height="534" loading="lazy" decoding="async"></div><figcaption><strong>Rendered email signature</strong> · The comment doesn't appear</figcaption></figure>
  </div>
</div>
