# Overview

Catalog is a collection of applications that a user can deploy to Kubernetes clusters as a workload template, a workload, or as a blueprint add-on. During the workload template/workload/add-on creation, users can choose from apps in a Catalog and add values.yaml files to the workload template/workload/add-on to override default values.

- Users can view the list of apps available in different category of catalog
- Select the required category from the **Filter by Category** drop-down (example: CMS, CRM, E-Learning, Forum, etc.)
- Select the required catalog from the **Filter by Catalog** drop-down. System catalogs (default-bitnami and default-helm) and the custom catalogs (repos created by users) are listed over here
