+### Setting up SSH Key
+
+Make sure to follow the below steps while creating SSH Keys and using them.
+The best practice is create the SSH Keys on local machine not remote machine.
+Login with username specified in Github Secrets. Generate a RSA Key-Pair:
+
+ ```bash
+ ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
+ ```
+
+Add newly generated key into Authorized keys. Read more about authorized keys [here](https://www.ssh.com/ssh/authorized_keys/).
+
+```bash
+cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
+```
+
+Copy Private Key content and paste in Github Secrets.
+
+```bash
+clip < ~/.ssh/id_rsa
+```
+
+See the detail information about [SSH login without password](http://www.linuxproblem.org/art_9.html)
