Feedback wanted: draft of a Clojure REPL guide, soon to be submitted on clojure.org

I don’t use Clojure REPL much. I feel this guide is too long. I don’t want to know every detail in Clojure REPL, but I want to know most of the tips that I would need in my real work. Tips like Boot can be external links. Installing Boot is not easy task also, why do I want to try Boot when I’m learning Clojure REPL.
