 there are kinks. Don't be afraid tho, I've been using it since 2011 with
 great success and much merriment.
 
+## Installation
+
+I highly recommend installing multiple-cursors through `package.el`.
+
+It's available on [melpa](http://melpa.milkbox.net/):
+
+    M-x package-install multiple-cursors
+
+The package depends on the `cl-lib` package, so if you do not use
+`package.el` or have a recent Emacs, you would need to install that
+too: see [GNU ELPA](http://elpa.gnu.org/packages/cl-lib.html).
