# Custom templates

When all the details have been entered, click **Create custom template**.

## Variables in templates

Custom templates support the use of variables to provide further customization of the deployed stack. A stack can define a variable that can then be adjusted by the user at deployment.

{% hint style="info" %}
This feature is only available in Portainer Business Edition.
{% endhint %}

Variables are identified in stacks with `{{ }}`. For example, the following stack provides a `MYSQL_PASSWORD` variable:

When a variable is defined, options appear to customize how the variable appears when deploying the stack. You can set the **label**, **description** and **default value**.

When a template is deployed, any variables that have been configured are editable:
