 To publish a managed application to your service catalog, you must:
 
-- Create a template that defines the resources to deploy with the managed application.
+- Create an Azure Resource Manager template (ARM template) that defines the resources to deploy with the managed application.
 - Define the user interface elements for the portal when deploying the managed application.
 - Create a _.zip_ package that contains the required template files.
 - Decide which user, group, or application needs access to the resource group in the user's subscription.
 - Create the managed application definition that points to the _.zip_ package and requests access for the identity.
 
+> [!NOTE]
+> Bicep files can't be used in a managed application. You must convert a Bicep file to ARM template JSON with the Bicep [build](../bicep/bicep-cli.md#build) command.

 Create a file named _mainTemplate.json_. The name is case-sensitive.

 ## Define your create experience
 
 As a publisher, you define the portal experience for creating the managed application. The _createUiDefinition.json_ file generates the portal interface. You define how users provide input for each parameter using [control elements](create-uidefinition-elements.md) including drop-downs, text boxes, and password boxes.
