+Hooks
+=====
+
+A *hook* is a list of functions that are executed when certain events
+happen.  Hooks are modified with the Emacs function ``add-hook``.
+Evil provides entry and exit hooks for all its states.  For example,
+when switching from normal state to insert state, all functions in
+``evil-normal-state-exit-hook`` and ``evil-insert-state-entry-hook``
+are executed.
+
+It is guaranteed that the exit hook will be executed before the entry
+hook on all state switches.
+
+During the hook execution, the variables ``evil-next-state`` and
+``evil-previous-state`` contain information about the states being
+switched to and from, respectively.
