+# Identify Outdated Gems
+
+Bundler can be used to identify outdated gems for a given project. By
+running `bundle outdated` in a project's directory, Bundler will compare the
+versions of all stated gem dependencies against the gem server and report a
+list of those gems that are not up to date.
+
+See the [Bundler docs](http://bundler.io/v1.1/bundle_outdated.html) for more
+details.
