A sample `oc apply` command which applies the default instance for this release of Kabanero, including the default collections, is shown when the `install.sh` script finishes running.  You can modify the CR instance to include the URL of a custom collection and the GitHub information necessary to administer that collection.

See link:/docs/ref/general/configuration/tekton-webhooks.html[Connecting Kabanero to GitHub with Tekton Webhooks] for instructions on deleting and creating webhooks.
 
 The **Kabanero Console** is installed as part of the install process and is a good next step to go explore information about your Kabanero instance.
