In the left pane, click Image Registry > Registry Projects.
On the Registry Projects page, click the name of a project. The detail page appears. This page has two sections:
To change a repository's description, click the pencil icon in the Description column. When the field opens, change the description, and then click the check mark.
To delete a repository, click its Actions menu, and then select Delete. When prompted, click Yes, delete!
