 That command will initialize a swarm with 1 manager who will listen on IP: 10.100.199.200:2377 for docker swarm related activities (advertise-addr) and income traffic (listen-addr)
+===Addition===
+To join a swarm a server must have the swarm's token. The token can be taken as follows:
-Manually the workers can be joined to the swarm as follows:
+<Code:none|Get Join Token for Manager & Worker>
+[root@mgr1 ~]# docker swarm join-token manager
+To add a manager to this swarm, run the following command:
+    docker swarm join --token SWMTKN-1-4mqe4htimsl9wrlzstzx6c18qmibjfjuuihdp3o91pnmssbvml-69b13glzhdgfzh58hbg7jwn69 10.100.199.200:2377

+Now, it is good idea to ALWAYS add the advertise and listener address to the server:
