-If a secret for joining new nodes is not provided with `--secret`, `docker swarm init` will
-generate a random one and print it to the terminal (as seen in the example above). To initialize
-a swarm with no secret, use `--secret ""`.
+`docker swarm init` generates two random tokens, a worker token and a manager token. When you join
+a new node to the swarm, the node joins as a worker or manager node based upon the token you pass
+to [swarm join](swarm_join.md).

-### `--auto-accept value`
-
-This flag controls node acceptance into the cluster. By default, `worker` nodes are
-automatically accepted by the cluster. This can be changed by specifying what kinds of nodes
-can be auto-accepted into the cluster. If auto-accept is not turned on, then
-[node accept](node_accept.md) can be used to explicitly accept a node into the cluster.
-
-For example, the following initializes a cluster with auto-acceptance of workers, but not managers
-
-
-```bash
-$ docker swarm init --listen-addr 192.168.99.121:2377 --auto-accept worker
-```
-
-It is possible to pass a comma-separated list of node types. The following initializes a cluster
-with auto-acceptance of both `worker` and `manager` nodes
-
-```bash
-$ docker swarm init --listen-addr 192.168.99.121:2377 --auto-accept worker,manager
-```
-
-To disable auto acceptance, use the `none` option. Note that this option cannot
-be combined with other values. When disabling auto acceptance, nodes must be
-manually accepted or rejected using `docker node accept` or `docker node rm`.
-
-The following example enables swarm mode with auto acceptance disabled:
-
-```bash
-$ docker swarm init --listen-addr 192.168.99.121:2377 --auto-accept none
-```
+After you create the swarm, you can display or rotate the token using
+[swarm join-token](swarm_join_token.md).

-Join a node to a Swarm cluster. If the `--manager` flag is specified, the docker engine

+Join a node to a swarm. The node joins as a manager node or worker node based upon the token you

+A cluster should only have 3-7 managers at most, because a majority of managers must be available
+for the cluster to function. Nodes that aren't meant to participate in this management quorum
+should join as workers instead. Managers should be stable hosts that have static IP addresses.

+Usage:	docker swarm join-token [--rotate] (worker|manager)
+
+Manage join tokens
+
+Options:
+      --help     Print usage
+  -q, --quiet    Only display token
+      --rotate   Rotate join token
+```
+
+Join tokens are secrets that determine whether or not a node will join the swarm as a manager node
+or a worker node. You pass the token using the `--token flag` when you run
+[swarm join](swarm_join.md). You can access the current tokens or rotate the tokens using
+`swarm join-token`.
+
+Run with only a single `worker` or `manager` argument, it will print a command for joining a new
+node to the swarm, including the necessary token:
+
+```bash
+$ docker swarm join-token worker
+To add a worker to this swarm, run the following command:
+    docker swarm join \
+    --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-1awxwuwd3z9j1z3puu7rcgdbx \
+    172.17.0.2:2377
+
+$ docker swarm join-token manager
+To add a manager to this swarm, run the following command:
+    docker swarm join \
+    --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-7p73s1dx5in4tatdymyhg9hu2 \
+    172.17.0.2:2377
+```
+
+Use the `--rotate` flag to generate a new join token for the specified role:
+
+```bash
+$ docker swarm join-token --rotate worker
+To add a worker to this swarm, run the following command:
+    docker swarm join \
+    --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-b30ljddcqhef9b9v4rs7mel7t \
+    172.17.0.2:2377
+```
+
+After using `--rotate`, only the new token will be valid for joining with the specified role.
+
+The `-q` (or `--quiet`) flag only prints the token:
+
+```bash
+$ docker swarm join-token -q worker
+SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-b30ljddcqhef9b9v4rs7mel7t
+```
+
+### `--rotate`
+
+Update the join token for a specified role with a new token and print the token.
+
+### `--quiet`
+
+Only print the token. Do not print a complete command for joining.
