+Samba Docker volume sharing plugin
+==================================
+
+Sharing a Docker container's volume should be as simple as `docker run niccokunzmann/samba-share <container> | sh`.
+
+This 'plugin' will create and configure a samba server container that auto-creates shares for all
+the volumes attached to the specified container.
+
+Usage
+-----
+
+Possible scenarios are
+
+- `docker run niccokunzmann/samba-share <container> | sh` shares the volumes of `<container>`.
+- `docker run niccokunzmann/samba-share` reminds the user what the options are.
+- Additional parameters can be [passed as environment variable](https://docs.docker.com/engine/reference/run/#env-environment-variables) and can be combined. Possible names are USER PASSWORD USERID GROUP READONLY RUN_ARGUMENTS. Examples: 
+
+        # run a samba server in read only mode
+        docker run -e READONLY=yes niccokunzmann/samba-share <container> | sh
+        # run a samba server on the host and share the content to other computers
+        docker run -e RUN_ARGUMENTS="--net=host" niccokunzmann/samba-share <container> | sh
+
+    - USER is the samba user (default: "root")
+    - PASSWORD is USER's password (default: "tcuser")
+    - USERID to use for the samba USER (default: "1000")
+    - GROUP user group (default: "root")
+    - READONLY "yes" or "no" whether write access is denied (default: "no")
+    - RUN_ARGUMENTS which additional arguments to pass to the `docker run ... samba-server` (default: "")
+
+    Warning: If you use a `\` in these variables, it could be removed or unescaped.
+
+Try it out
+----------
+
+Create a volume in my-data and share its content via samba
+
+    # Make a volume container (only need to do this once)
+    docker run -v /data --name my-data busybox true
+    # Share it using Samba (Windows file sharing)
+    docker run niccokunzmann/samba-share my-data | sh
+
+How it works
+------------
+
+The `niccokunzmann/samba-share` container uses the bind-mounted docker client and socket to introspect
+the configuration of the specified container and, then uses that information to setup a new container
+that is `--volumes-from` setup to give it access.
