+** Using hydra
+This module provides a batteries-included hydra - ~+ein-hydra~ - to make using ein
+easier. Things like navigating between cells, workbook management etc, are greatly
+simplified and are easily accessible. However, by default, it's not bound to any key.
+Here's an example of how to bind it:
+
+#+BEGIN_SRC emacs-lisp
+(map!
+  (:map ein:notebook-mode-map
+   :localleader
+   :map ein:notebook-mode-map "," #'+ein-hydra/body))
