+** Cider mode
+
+   Cider is like Slime for Common Lisp. This configuration is copied

+
+   #+BEGIN_SRC emacs-lisp
+     (ensure-library cider)
+   #+END_SRC
+
+   Provides minibuffer documentation for the code you're typing into
+   the repl.

+   #+END_SRC
+
+   When there's a cider error, show its buffer and switch to it.
