--- title: Marketplace catalog slug: edgemanager/lem-user-guide/deploy-applications/marketplace-catalog description: The Marketplace is a catalog repository. You can then deploy applications from each catalog. docTags: createdAt: 2022-11-24T19:07:17.000Z --- The Marketplace is a catalog repository that includes a default catalog. A catalog is a collection of Docker applications that can be configured as needed before being deployed to Litmus Edge instances. You can deploy both public and private catalogs, and then deploy applications for various uses. The default catalog is preloaded with applications, such as visualization, user interface reporting, business intelligence, programming, server, and database tools. From the Marketplace Catalog browser pane, you can add, edit, or delete marketplace catalogs. You can modify the default marketplace catalog, but not delete it. Access to Marketplace depends on the Marketplace role that an administrator assigns to your user account: - **Observer**: You can view catalogs, applications, releases, and registries. You cannot create, edit, import, export, or deploy. - **Administrator**: You have full access, including managing shared registries. If your account has neither role, you cannot open Marketplace. To assign roles, see Edit a user profile. :::hint{type="info"} **Note:** When you upgrade from Litmus Edge Manager 2.x to 3.0.0, all existing users receive the administrator Marketplace role. ::: ## Access marketplace **To access the marketplace:** 1.
