# Reverse ETL

Detailed technical documentation on RudderStack's Reverse ETL feature.

RudderStack's **Reverse ETL** feature lets you use the customer data residing in your data warehouse and route it to your entire data stack, including analytics, sales, and marketing tools.

With this feature, you can set up your data warehouse as a source in the [RudderStack dashboard](https://app.rudderstack.com/), choose the data to import, and then sync it to your desired destination.
