# How to perform static segmentation
1. Log in to the panel and go to the **Contacts -> Group List** tab.
2. Click the **Group Segmentation** button to open the tool.
3. Decide whether you want to create a **New group** or modify an **Existing group**. If you are creating a new group, enter a name for it.
4. From the list, select the type of action you want to perform (e.g., `Add contacts from another groups`).
5. Depending on the chosen operation, select the group or groups of contacts you want to operate on and define the segmentation parameters.
6. Click the **Segmentize** button. After a moment, the new or updated group will appear on your list in the **Contacts -> Group List** tab. You can track the status of the operation in the **List of operations** section.

## 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.messageflow.com/contacts/contact-segmentation/static-segmentation/how-to-perform-static-segmentation.md?ask=&goal=
```
`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.
