 Updating a dependency
 ---------------------
 
-Given we use [npm shrinkwrap][shrinkwrap], we have to take extra steps to make
-sure the `npm-shrinkwrap.json` file gets updated correctly when we update a
-dependency.

-Use the following steps to ensure everything goes flawlessly:
-
-- Run `make electron-develop` to ensure you don't have extraneous dependencies
-  you might have brought during development, or you are running older
-  dependencies because you come from another branch or reference.
-
-- Install the new version of the dependency. For example: `npm install --save
-  [package]@[version]`. This will update the `npm-shrinkwrap.json` file.

-- Commit *both* `package.json` and `npm-shrinkwrap.json`.
