# The Capture Tag

In [Liquid markup](/v1/docs/getting-started-with-liquid-markup), the `capture` tag saves content as a new variable that you can use.

While superficially similar to the `assign` tag, `capture` allows you to, aptly, *capture* multi-line content, HTML and other liquid markup. Think of the `capture` tag as storing a detailed list that you can reference elsewhere.

Here’s an explanation by way of a non-Slate example:

Imagine that you have 12 Slate Sharks and you want to keep a detailed list of what you’re going to do with those Sharks:

- Count the Sharks
- Decide how many you might want to keep, or give away
- Write a message like “I have 12 Slate Sharks, but I know I want to give some away, but I must keep 2 for myself.”

You could *capture* all of these thoughts in one `capture` tag format them as an HTML list:

```xml
{% capture slate-shark-information %}
<ul>
    <li>Count the Sharks</li> 
    <li>Decide how many you might want to keep, or give away</li>
    <li>Write a message like “I have 12 Slate Sharks, but I know I want to give some away, but I must keep 2 for myself.”</li>
</ul>
{% endcapture %}
```

The HTML `&lt;ul&gt;` (unordered list) and `&lt;li&gt;` (list item) tags are preserved and print the items as a bulleted list.

You can now print this content any time you call the merge field we designated with the opening tag, `{{slate-shark-information}}`.

## How to use capture

The `capture` tag defines a variable that stores content.

Any content between `{% capture %}` and `{% endcapture %}` is stored as a string and assigned to that particular variable name:

```plaintext
{% capture signature %}
    {{User-First}} {{User-Last}}
    {{User-Title}}
    Slate University
{% endcapture %}
```

In this example, we have a `capture` tag with a variable name `signature`.

The tag stores three lines of text, containing values for the fields *User First*, *User Last*, *Title* and the text *Slate University*.

The captured content appears wherever in the document we use `{{signature}}`.
