+Usage:  docker plugin create [OPTIONS] reponame[:tag] PATH-TO-ROOTFS
+
+create a plugin from the given PATH-TO-ROOTFS, which contains the plugin's root filesystem and the manifest file, manifest.json
+
+Options:
+      --compress   Compress the context using gzip 
+      --help       Print usage
+```
+
+Creates a plugin. Before creating the plugin, prepare the plugin's root filesystem as well as
+the manifest.json (https://github.com/docker/docker/blob/master/docs/extend/manifest.md)
+
+
+The following example shows how to create a sample `plugin`.
+
+```bash
+
+$ ls -ls /home/pluginDir
+
+4 -rw-r--r--  1 root root 431 Nov  7 01:40 manifest.json
+0 drwxr-xr-x 19 root root 420 Nov  7 01:40 rootfs
+
+$ docker plugin create plugin /home/pluginDir
+plugin
+
+NAME                  	TAG                 DESCRIPTION                  ENABLED
+plugin                  latest              A sample plugin for Docker   true
+```
+
+The plugin can subsequently be enabled for local use or pushed to the public registry.
