 You can create a swarm of one manager node, but you cannot have a worker node without at least one manager node. By default, all managers are also workers.
 
 
+== Create swarm
 
+Initialize a swarm. The docker engine targeted by this command becomes a manager in the newly created single-node swarm.

+Swarm initialized: current node (bvz81updecsj6wjz393c09vti) is now a manager.

+=== Join token
+
+Join tokens are secrets that allow a node to join the swarm. 
+
+There are two different join tokens available,

+- one for the worker role and 
+- one for the manager role.

+=== Join swarm
+
+Join a node to a swarm. The node joins as a manager node or worker node based upon the token you pass with the --token flag. If you pass a manager token, the node joins as a manager. If you pass a worker token, the node joins as a worker.

+
+The safe way to remove a manager from a swarm is to *demote* it to a worker and then direct it to leave the quorum without using --force
