+See the `container.json` file for what the configuration should look like.
 
 Using this configuration and the current directory holding the rootfs for a process, one can use libcontainer to exec the container. Running the life of the namespace, a `pid` file 
 is written to the current directory with the pid of the namespaced process to the external world.  A client can use this pid to wait, kill, or perform other operation with the container.  If a user tries to run a new process inside an existing container with a live namespace, the namespace will be joined by the new process.
 
-
 You may also specify an alternate root place where the `container.json` file is read and where the `pid` file will be saved.
