A note for Windows users (CLICK to expand)

You may practice Linux CLI on your Windows machine using Git Bash that gets installed along with [Git](https://git-scm.com/downloads). To open Git Bash right click anywhere in file explorer and select `Git Bash here` option. Bash will get opened in context of the directory you called it at. 

When completed

Proceed to Git basics
