+We highly recommend to append this command to your `/init` script.
+
+### Multiple Sessions using ssh
+
+If you need multiple sessions, a ssh server should be prepared inside the FastModel.
+To enable ssh connections for `root` user, please follow the below instructions.
+
+```console
+sh-3.2# passwd
+sh-3.2# ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
+sh-3.2# vi /etc/ssh/sshd_config
+. . . Omission . . .
+PermitRootLogin yes
+```
+
+After that, you can start the ssh daemon inside the FastModel. This can be also appended to your `/init` script.
+```console
+sh-3.2# /usr/sbin/sshd
+```
+
+Then, ssh connections from Host PC can be established with 8022 port (i.e., port forwarding).
+```console
+$ ssh root@localhost -p 8022
+root@localhost's password:
+Welcome to Tizen
+root:~>
+```
+
 ### Package Installation
