# Getting started with notifications
<a name="getting-started"></a>

The easiest way to get started with notifications is to set up a notification rule on one of your build projects, deployment applications, pipelines, or repositories.

**Note**  
The first time you create a notification rule, a service-linked role is created in your account. For more information, see [Using service-linked roles for AWS CodeStar Notifications](using-service-linked-roles.md).
