# Looker

This feature provides a comprehensive impact analysis of dbt™ changes on your Looker environment. When you open a pull request (PR) in your dbt™ project, you can visualize the downstream effects of your changes across various Looker assets.

### Key Benefits:

1. Identify which dbt™ model changes are impacting your Looker assets.
2. Proactively communicate which Looker measures and dimensions are affected by your dbt™ changes before going into production
3. Discover which dashboards and looks might be impacted by the changes

### Prerequisites:

1. Complete [Lineage Diff setup prerequisites](https://docs.paradime.io/app-help/documentation/bolt/ci-cd/lineage-diff/..#setup-instructions)
2. Connect Looker to Paradime via the  [Looker Integration](https://docs.paradime.io/app-help/documentation/integrations/dashboards/looker)

## How to Use <a href="#how-turbo-ci-works" id="how-turbo-ci-works"></a>

When a PR is opened in GitHub, an automated comment is generated listing all downstream Looker nodes (Views, Explores, Looks, Dashboards, etc.) that would be impacted.

Using the links available in the "Looker Nodes Impacted" section, you can confidently investigate each node within looker before merging the PR changes into production.
