The requirements and process for setting up your Service Broker catalog depends on the content that you are providing to your users.
Each process is provided as an end-to-end procedure. Identify the content that you are providing and add each relevant type. Ensure that the imported content is working properly outside of Service Broker before you add it to the catalog.
After you add the content sources, the templates are refreshed every six hours. Any changes to the templates in your external sources are reflected in the catalog after a refresh.
