# Sigma

Integrate, catalog, and govern Sigma assets in Atlan.

## Required permissions

- [Preflight checks for Sigma](https://docs.atlan.com/llms/connectors/sigma/preflight-checks-for-sigma/llms.txt): First, the list of workbooks in the _Include Workbooks_ and _Exclude Workbooks_ fields is determined. Next, the List Workbooks REST API is used to fetch the actual list of workbooks for which the user credentials have view permission.

## Setup options

- [Set up Sigma](https://docs.atlan.com/llms/connectors/sigma/set-up-sigma/llms.txt): :::warning Who can do this? You will probably need your Sigma administrator to complete these steps - you may not have access yourself.

## Crawl and mine
