 Rust mode will automatically be associated with .rs and .rc files. To
 enable it explicitly, do `M-x rust-mode`.

+### package.el installation via Marmalade
+
+It can be more convenient to use Emacs's package manager to handle
+installation for you if you use many elisp libraries. If you have
+package.el but haven't added Marmalade, the community package source,
+yet, add this to ~/.emacs.d/init.el:
+
+```lisp
+(require 'package)
+(add-to-list 'package-archives
+             '("marmalade" . "http://marmalade-repo.org/packages/"))
+(package-initialize)
+```
+
+Then do this to load the package listing:
+
+* <kbd>M-x eval-buffer</kbd>
+* <kbd>M-x package-refresh-contents</kbd>
+
+If you use a version of Emacs prior to 24 that doesn't include
+package.el, you can get it from http://bit.ly/pkg-el23.
+
+If you have an older ELPA package.el installed from tromey.com, you
+should upgrade in order to support installation from multiple sources.
+The ELPA archive is deprecated and no longer accepting new packages,
+so the version there (1.7.1) is very outdated.
+
+From there you can install rust-mode or any other modes by choosing
+them from a list:
+
+* <kbd>M-x package-list-packages</kbd>
+
+Now, to install packages, move your cursor to them and press i. This
+will mark the packages for installation. When you're done with
+marking, press x, and ELPA will install the packages for you (under
+~/.emacs.d/elpa/).
+
+* or using <kbd>M-x package-install rust-mode
+
+#### Important
+
+In order to have cm-mode properly initialized after compilation prior
+to rust-mode.el compilation you will need to add these `advices` to
+your init file or if you are a melpa user install the `melpa` package.
+
+```lisp
+(defadvice package-download-tar
+  (after package-download-tar-initialize activate compile)
+  "initialize the package after compilation"
+  (package-initialize))
+
+(defadvice package-download-single
+  (after package-download-single-initialize activate compile)
+  "initialize the package after compilation"
+  (package-initialize))
+```
