Before workshop

Install leiningen

For linux install rlwrap sudo apt-get install rlwrap

Install some text editor preferably Light table

Run some commands to download stuff to prevent jaming wifi at once

Download and start clojure repl

• lein repl
• wait to start

For clojurescript development use re-frame template

• lein new re-frame <project-name>
• cd <project-name>
• lein figwheel dev
• wait

Or if you want only clojurescript repl without web stuff (on node for example). https://github.com/clojure/clojurescript/wiki/Quick-Start
