*Article Topics:* [*Sites*](/getting-started/common-topics/sites.md)*,* [*Templates*](/getting-started/common-topics/templates.md)

## Editing Templates

To test your templates, navigate to the [Sites Admin](/nats-admin/sites.md) and select the Site & Tour you wish to perform your tests for.

## Using the TPL Function

Once your Templates have been created and customized, you can then begin testing them. To test your templates, use the format below inserting your [link domain](/using-nats/nats-admin-features/linkdomain.md) and the [linkcode](/using-nats/nats-admin-features/linkcodes.md) followed by **"tpl=page"** where **page** is the template name found in the [template tab ](/nats-admin/sites/site-management/tour-overview.md#templates-tab)of the tour you wish to view.&#x20;

{% code overflow="wrap" %}

```

```

{% endcode %}
