...and welcome to this little tutorial of mine. Lua is a simple programming/scripting language meant for coding, well, simple things.
Throughout this tutorial, you may want to try out some code on your own. For this, I suggest using the website repl.it.
You can create an account for free, and use it to run various simple programs on many programming languages, including Lua. It'll also automatically save your programs for you.
I suggest using it to try out some code on your own throughout this tutorial. It'll be worth it, trust me.
To the right of the screen, past the Lua logo, you will see the index. That'll lead you to different parts of the tutorial. Enjoy!
