This looks good to me, for the most part. I just have a couple issues with inconsistent indentation that I'd like to get cleaned up beforehand. 🙂

@Snuggle I don't know why my editor (VS Code) is doing this. 🤯
My VS Code is configured to insert 4 spaces when tab is pressed.
What editor do you guys use?

[Snuggle]

I usually use micro for editing shell files, but I have made similar mistakes in the past. I think it's mostly something you'll have to pay attention to.

Micro is similar to nano, but has a lot more awesome features like copy/paste, ctrl + c/v shortcuts, automatic syntax highlighting and smart sudo.

[Snuggle]

This part is all over the place! The first two lines are at completely different indentation levels to the rest of this test.

[jskrnbindra]

@Snuggle I think this should do. Had to do in a trial-error way.
I'll setup micro.

Woo! Things now look pretty and I'm happy now! ✨

Now to see if @matchai has any more comments or feedback before being merged. 😊

@jskrnbindra I also use VSCode. Be sure to install the EditorConfig extension, which will read the .editorconfig file in the project root and use the correct indentation. 😄

Just a few quick changes ☝️ 😄

@Snuggle @matchai Got a bit occupied, I'm travelling. Will do it in a couple of days.
