I published a video on repl driven development with Spacemacs, which should also be useful to help learn some of the features of CIDER too. The commands used to drive CIDER are shown in the mode line, so you can follow along if using Prelude or your own Emacs configuration.

(and thanks to @bozhidar for making CIDER and then making it awesome).
