+This is for setting up the shortcut commands in Mac terminal
+For example, if I type ```cts``` in my terminal, it will directly link to the lab server
+How?
+1. I used oh-my-zsh from here https://ohmyz.sh/ but it would work for regular terminals too
+2a. If you use oh-my-zsh: You find ```~/.zshrc```.
+2b. If you just use default terminal, just open ```~/.bash_profile```.
+3. I installed Atom as my text editor so I can open it from my terminal ```atom ~/.zshrc``` to edit it. But any text editor tools would work. If you open it from your desktop, you may need to view invisible files to see it.
+4. Add under "alias" and save the file. For example ```alias cts = "ssh [email protected]"```. Next time, I entered ```cts``` in my terminal, it would directly execute the command.
