+If you're not familiar with Lisp or Clojure, here's a short video on
+how the tooling for Lisp (and hence Clojure) is great and enables fast
+developer feedback and high quality applications. Initially, the video
+was created to answer a [[https://github.com/200ok-ch/org-parser/issues/4][specific issue]] on this repository. However, the question is a valid
+general question that is asked quite often by people who haven't used
+a Lisp before.
