On another note: maybe if the installation of ClojureScript would be manageable in, say, an hours instead of having to search half a day among outdated information, more people would try it (and this is from someone who already uses Clojure and Leiningen a bit).
Clojure and its libraries has the worst documentation, and this malpractice seems to be continued in ClojureScript.
https://github.com/magomimmo/modern-cljs is how I got started with Cljs. If you scroll down, you'll see some tutorials that get you set up and lead you to a workflow.
I had a few teething problems getting it configured properly, but I managed to get ClojureScript working from scratch on a Windows machine in about an hour, I think. What problems did you have? (Mine were Java related)
