# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.jentis.com/jentis-dcp-elements/account-settings/container-administration/create-a-container.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
