+runc is a command line client for running applications packaged according to
+the Open Container Format (OCF) and is a compliant implementation of the
+Open Container Initiative specification.
+
+runc integrates well with existing process supervisors to provide a production
+container runtime environment for applications. It can be used with your
+existing process monitoring tools and the container will be spawned as a
+direct child of the process supervisor.
+
+Containers are configured using bundles. A bundle for a container is a directory
+that includes a specification file named "` + specConfig + `" and a root filesystem.
+The root filesystem contains the contents of the container. 
+
+To start a new instance of a container:
+
+    # runc start [ -b bundle ] <container-id>
+
+Where "<container-id>" is your name for the instance of the container that you
+are starting. The name you provide for the container instance must be unique on
+your host. Providing the bundle directory using "-b" is optional. The default
+value for "bundle" is the current directory.`
