# Create a List

Lists can be created and modified to be used in scripts and War Rooms. A list can contain items of the same type in any format that would be useful. These are later parsed by, and can be modified by, scripts. For example, you might need to create a list of emails, a list of known trusted IPs (allow list), JSON objects, etc.

1. Select Settings → Advanced → Lists → **Add a List**.
2. Type the name of the list.
3. From the dropdown list, select the Content Type.
4. (Multi-tenant) From the dropdown list, select the propagation labels to propagate the list to the relevant tenants.
5. Add the content as required. For an example of a JSON list and how to use it, see [Work with JSON Lists](/xsoar-6-administrator-guide/6.13/learn-about-cortex-xsoar/customize-and-configure-cortex-xsoar/lists/work-with-lists/work-with-json-lists.md).
6. To restrict access to the list, in the **Permissions** section, select the **Read Only** and **Read and edit** [roles](/xsoar-6-administrator-guide/6.13/learn-about-cortex-xsoar/onboarding-in-cortex-xsoar/users-and-roles/roles-in-cortex-xsoar.md).
7. Save the list.

## 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://cortex-docs.paloaltonetworks.com/xsoar-6-administrator-guide/6.13/learn-about-cortex-xsoar/customize-and-configure-cortex-xsoar/lists/create-a-list.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.
