+## The command line
 
 The command line - or shell - is a text interface for your computer.
 It's a program that takes in commands, which it passes on to the
 computer's operating system to run.
 
-## RStudio terminal
+
+-   Windows PowerShell is a command-line in windows. It uses bash-like commands unlike the Command Prompt which uses dos commands (a sort of windows only language). You can open is by going to Start | Windows PowerShell or by searching for it in the search bar.
+
+- Terminal is the command line in Mac OS X. You can open it by going to Applications | Utilities | Terminal or by searching for it in the Spotlight search bar.
+
+-   git bash. I used the bash shell that comes with [Git](https://git-scm.com/)
+
+### RStudio terminal
 
 The RStudio terminal is a convenient interface to the shell without
 leaving RStudio. It is useful for running commands that are not
 available in R. For example, you can use it to run other programs like
 fasqc, git, ftp, ssh
