Technical requirements

For these recipes, we're going to use a Linux machine. We can use any virtual machine from our previous recipe. For example, let's say that we're going to use a cli1 virtual machine as it's the most convenient to use, seeing as it's a command-line-interface-only machine. So, all in all, we need the following:

• A virtual machine with any distribution of Linux installed (in our case, it's going to be Ubuntu 20.10).
• A bit of time to digest the complexities of using the Vi(m) editor. nano is less complex; therefore, it's going to be easier to learn about that one.

So, start your virtual machine and let's get cracking!
