+### package
 
+This section explains how to install rustic with the default package manager.
 It's necessary to include elpa for a package dependency:
 
 ```elisp
+(require 'package)
 (setq package-archives '(("melpa" . "http://melpa.org/packages/")
                          ("gnu" . "http://elpa.gnu.org/packages/")))
+(package-initialize)
+(package-refresh-contents)
+(use-package rustic)
 ```
 
 If ‘spinner-1.7.3’ is unavailable” when trying to install rustic, you
 need to update GPG keys used by the ELPA package manager. Try
 installing
 [gnu-elpa-keyring-update](https://elpa.gnu.org/packages/gnu-elpa-keyring-update.html).
