Using LightTable

LightTable has an online tutorial entitled Getting started with LightTable

I create a project first with Leiningen, open the project directory in the LightTable workspace and open any files I want to work with. I then connect the open editor window for the file by pressing Ctrl-Enter at the end of an expression.

my approach is documented in the quick demo section of my Clojure & LightTable slides from JAXLondon 2013.
