| # Using OpenWhisk-enabled services |
| |
| In OpenWhisk, a catalog of packages gives you an easy way to enhance your app with useful capabilities, and to access external services in the ecosystem. Examples of external services that are OpenWhisk-enabled include Cloudant, The Weather Company, Slack, and GitHub. |
| |
| The catalog is available as packages in the `/whisk.system` namespace. See [Browsing packages](./packages.md#browsing-packages) for information about how to browse the catalog by using the command line tool. |
