+## Filtering
+
+The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
+than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
+
+The currently supported filters are:
+
+* name
+* id
+* label
+* desired_state
+
+### name
+
+The `name` filter matches on all or part of a tasks's name.
+
+The following filter matches the node with a name equal to `swarm-master` string.
+
+    $ docker node ls -f name=swarm-master
+    ID              NAME          STATUS  AVAILABILITY      MANAGER STATUS  LEADER
+    0gac67oclbxq *  swarm-master  Ready   Active            Reachable       Yes
+
+### id
+
+The `id` filter matches all or part of a node's id.
+
+    $ docker node ls -f id=0
+    ID              NAME           STATUS  AVAILABILITY     MANAGER STATUS  LEADER

+    0pwvm3ve66q7    swarm-node-02  Ready   Active
+
+
+#### label
+
+The `label` filter matches tasks based on the presence of a `label` alone or a `label` and a
+value.
+
+The following filter matches nodes with the `usage` label regardless of its value.
+
+```bash
+$ docker node ls -f "label=foo"
+ID              NAME           STATUS  AVAILABILITY     MANAGER STATUS  LEADER

+###	--auto-accept value
+
+This flag controls node acceptance into the cluster. By default, both `worker` and `manager`
+nodes are auto accepted by the cluster. This can be changed by specifing 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
+Initializing a new swarm
+```
+
+### `--force-new-cluster`
+
+This flag forces an existing node that was part of a quorum that was lost to restart as a single node Manager without losing its data
+
+### `--listen-addr value`
+
+The node listens for inbound Swarm manager traffic on this IP:PORT
+
+### `--secret string`
+
+Secret value needed to accept nodes into the Swarm

+# swarm join
+
+	Usage:	docker swarm join [OPTIONS] HOST:PORT
+
+	Join a Swarm as a node and/or manager.
+
+	Options:
+	      --help                Print usage
+	      --listen-addr value   Listen address (default 0.0.0.0:2377)
+	      --manager             Try joining as a manager.
+	      --secret string       Secret for node acceptance
+
+Join a node to a Swarm cluster. If the `--manager` flag is specified, the docker engine
+targeted by this command becomes a `manager`. If it is not specified, it becomes a `worker`.
+
