    Scheme Made Easy▲6

    In past few weeks, I wrote several chapters to learn Scheme, a programming language of the Lisp dialect. The writing is not final as many chapters are missing. I wrote this because I wanted to improve my Scheme knowledge and increase the (low) number of Scheme literature. The writing is inspired by Calculus Made Easy, which I learned about here on HN. This is why I'm sharing it here. But keep in mind that my writing style is not as good as that in the above-mentioned inspiration. Feedback is very much appreciated.
