# OSGi Frameworks Preferences

You can configure the default OSGi Framework for new OSGi Framework launchers using the Window > Preferences... > Plug-in Development > OSGi Frameworks preference page.

## OSGi Framework Selection

All available OSGi Frameworks are listed in the Installed OSGi Frameworks table. To contribute an OSGi Framework, the plug-in containing the framework implementation must contain an `org.eclipse.pde.ui.osgiFrameworks` extension.

To set a framework as the default for new OSGi Framework launch configurations, select the framework entry in the table and click the Set as Default button.
