# Looker

Integrate, catalog, and govern Looker assets in Atlan.

## Required permissions

- [Preflight checks for Looker](https://docs.atlan.com/llms/connectors/looker/preflight-checks-for-looker/llms.txt): First, the list of projects in the _Include Projects_ and _Exclude Projects_ fields is determined. Next, the Query Projects REST API is used to fetch the actual list of projects for which the user has view capability.

## Setup options

- [Set up Looker](https://docs.atlan.com/llms/connectors/looker/set-up-looker/llms.txt): :::warning Who can do this? You probably need your Looker administrator to run these commands - you may not have access yourself.
- [Set up on-premises Looker access](https://docs.atlan.com/llms/connectors/looker/set-up-on-premises-looker-access/llms.txt): In some cases you won't be able to expose your Looker instance for Atlan to crawl and ingest metadata. For example, this may happen when security requirements restrict access to sensitive, mission-critical data.

## Crawl and mine

- [Crawl Looker](https://docs.atlan.com/llms/connectors/looker/crawl-looker/llms.txt): Once you have configured the Looker user permissions, you can establish a connection between Atlan and Looker.
- [Crawl on-premises Looker](https://docs.atlan.com/llms/connectors/looker/crawl-on-premises-looker/llms.txt): Extract metadata from on-premises Looker to catalog dashboards, looks, explores, and data sources. Discover and govern your BI assets after configuring extractor tool.

## Reference

- [What does Atlan crawl from Looker?](https://docs.atlan.com/llms/connectors/looker/what-does-atlan-crawl-from-looker/llms.txt): During a Looker crawl, Atlan extracts metadata for Connections, Projects, Views, Models, Folders, Looks, Dashboards, Tiles, and Explores. Reference tables map each Looker property to its Atlan asset.
- [Looker assets package](https://docs.atlan.com/llms/connectors/looker/package-reference/llms.txt): Programmatically crawl and manage Looker assets in Atlan using the Python SDK (pyatlan). Reference for the Looker assets package.
