# Variables

<Info>
  All supported variables are listed here in the Fossabot documentation!
</Info>

Variables offer inline, dynamic text replacement for Fossabot responses.

## Usage

Use the `$()` syntax within your chat responses to insert dynamic data.

For example, [**\$(sender)**](/docs/variables/sender) allows you to mention the name of the user triggering the action, you may choose to invoke this variable within a command such as `Hello, $(sender)!`. See the below example for more details.

## Example

A command with the following configuration:

...would produce the following output in [**Twitch**](https://twitch.tv) chat.
