For more information about the App Repo, see [ServiceNow application repository](https://www.servicenow.com/docs/S~qkI6Li8JtSw_8B8LsNHA "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.").
