+## Example
+
+The following example illustrates an interactive uninstall.
+
+1. Run the uninstall command.
+
+        $ docker run --rm -it -v /var/run/docker.sock:/var/run/docker.sock --name ucp docker/ucp uninstall -i
+        INFO[0000] We're about to uninstall the local components for UCP ID: FEY4:M46O:7OUS:QQA4:HLR3:4HRD:IUTH:LC2W:QPRE:BLYH:UWEM:3TYV

+        INFO[0005] Removing UCP volumes                         
+
+2. List the images remaining on the node.
+
+    Because the `ucp` tool is running during the installation, it can't remove
+    its own image. Until you remove that image, the node continues to appear in
+    the UCP dashboard.
+
+        $ docker images
+        REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
