 When you are faced with operating a machine via the command line for the first time, this can be confusing and frustrating. This document aims to show you some of the basic principles of using a command line instead of a graphical interface. We will guide you through a series of hands-on exercises to practice some of the main commands you need to get started.
 
-In this document, we cover commands for a **Linux** command line. If you are using a Windows command line, we recommend that you [refer to the Windows documentation](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/windows-commands), as the commands differ. In the context of virtual machines and servers, a Linux-based OS is generally the go-to choice. Unlike Windows, Linux OSes do not require paid-for licenses, they are free and open source.
