+At moments like these, it's convenient to have a reasonably up to date state of recent files, bookmarks, history variables, etc. available when you restart Emacs again. Normally these items are executed at Emacs exit (as part of =kill-emacs-hook=), but when Emacs exits unexpectedly due to a crash, these functions are not executed and you're left with an outdated state (if any).
 
 This package allows you to execute a function at a regular interval. To minimize any disturbance while you're working, a few seconds of idleness will trigger the execution of all save functions.

 * Installation and usage
 
-Clone the repository and put the package in your =load-path=.
+At this moment, there is no MELPA package. Therefore, clone the repository and put the package in your =load-path=, for example with =use-package=:
 
 #+begin_src elisp
   (use-package persist-state

 Then, add functions to =persist-state-functions= which should be executed, e.g. to save bookmarks at regular intervals:
