NOTES CLIENT INSTALLATION AND UPGRADE
You can create the deployment widget directly in the catalog, as described here, or create the widget using a configuration wizard and then publish the widget to the catalog.
Note The Start Configuring Widgets wizard dialog contains a Features and Plugins option. This option launches a wizard sequence designed to simplify the process of creating a Notes client plug-in deployment widget. The wizard guides you through the widget definition and extension.xml creation process. For details, see "Configuring a new Features and Plugins deployment widget" in Notes 8.5 and greater help.
1. Open the widgets catalog by clicking Browse the Widget Catalog button in the My Widgets sidebar panel toolbar.
2. Create the widget.
