The end. You made it. Congratulations. You've managed to read the entirety of "The 10 Minute Squircle Hack" in 10 minutes flat. I'm sure your brain is still recovering from the trauma.
For those who didn't quite make it, don't worry. The first chapter is still available at Episode 1: The Beginning of the End. Or, if you're feeling particularly adventurous, you can try to tackle the infamous Appendix: A Brief History of Squircle Mathematics, where you can learn all about the ancient art of squircle geometry.
Or, if you're just feeling lazy, you can just go back to the beginning and try again. We won't judge you.
