# Audience Builder: Source Picker

> This article will outline what the Source Picker is and what it is used for

When building an Audience, we start with the broadest category of information and gradually get more specific. This begins with the broadest category of the data within Hatch, the Source.

### Example of the Source Picker

When you click the Source Picker drop-down, you will see a list of all data sources that at least one contact has in your Hatch account.

**Hatch Contact** will always exist and will allow you to search for things like Name, Phone, Email, and other data that is associated to a Hatch Contact.

If you are looking for contacts from your CRM, you will see the source name listed *.*

If you have a CRM that is handled by the Data Team, the source will be  *CSV Import*.
