+How to install gyp-mode for emacs:
+
+Add the following to your ~/.emacs (replace ... with the path to your gyp
+checkout).
+
+(setq load-path (cons ".../tools/emacs" load-path))
+(require 'gyp)
+
+Restart emacs (or eval-region the added lines) and you should be all set.
+
+Please note that ert is required for running the tests, which is included in
+Emacs 24, or available separately from https://github.com/ohler/ert
