+** Counsel
+~ivy-mode~ ensures that any Emacs command using ~completing-read-function~ uses ivy for completion.
+
+Counsel takes this further, providing versions of common Emacs commands that are customised to make the best use of Ivy. For example, ~counsel-find-file~ has some additional keybindings. Pressing ~DEL~ will move you to the parent directory.
