# Example Plugin: Sidebar Items

This example plugin places two items with the title "Feedback" in the
sidebar; one as a top-level entry, and the other is placed under the
cluster item. It also removes the Namespaces sidebar item and route.

```bash
cd plugins/examples/sidebar
npm install
npm start
# See the sidebar on the left of Headlamp has changed.
