# Create a Container

You can create a new container on the JENTIS Platform in three easy steps: **Basic Settings**, **Advanced Settings**, and **Tracking Configuration**. Navigate to the **Settings** menu, go to the **Containers** section, and click on **Add New Container** to start your new container configuration.

In the basic settings, you will configure:

* **Container name** – A descriptive name for your container.
* **Website domain** – The URL of the domain to connect to the container, f.e., `example.com`.

{% hint style="warning" %}
Be aware that you can not change the **website domain once the container is created**.
{% endhint %}

* *Optional:* **Consentbar (CMP)** – Select from the list of supported consent bars. To activate tracking, you must configure your CMP on the **Legal Hub** menu. For more information, read [JENTIS CMP Connectors](/consent-center/how-jentis-handles-consent/jentis-cmp-connectors.md)
* *Optional:* **Cookie Lifetime Extender** - This feature allows you to preserve cookie duration in the face of browsers' privacy restrictions, such as Safari’s ITP, ensuring your tracking remains accurate, durable, and compliant.

In the advanced settings, you can optionally configure:

* **Preview URL** – Set a custom URL instead of the website domain for the container configuration preview session. If this field is left empty, the **website domain** configured on the basic settings will be used.
* **Main Domain Cookie** - This feature allows you to configure whether first-party identifiers (e.g., JENTIS User-ID) are implemented at your website’s main domain or subdomain level in your containers. This enables the identification of users across the main domain and its subdomains. For more information, read: [Main Domain Cookie](/key-features/main-domain-cookie.md)

Click on the **Create** button to save your new container.
