Publish changes that you have made to an app in ServiceNow Studio to the Application Repository (App Repo).

## Before you begin

Role required: admin or delegated developer

## About this task

The App Repo is one option ServiceNow offers for app deployment. You can also [create update sets](https://www.servicenow.com/docs/6nWS4jewnC0qjOr~GMyJXA "Create an update set as you work in ServiceNow Studio.") to publish changes, or if your company has a deployment pipeline set up, you can deploy changes through the pipeline in ServiceNow Studio. For more information about the App Repo, see [ServiceNow application repository](https://www.servicenow.com/docs/GPzhZ2fTLeFKG11v0urMJg "After you develop and test a custom application, you can make the application available to company instances by publishing it to the ServiceNow application repository.").

## Procedure

2. Open the App details page for the application that you want to update from either the ServiceNow Studio home page or the Navigator panel.
   * On the ServiceNow Studio home page, select the Deployment tab. Then select Applications and select your application from the Name column.
