-# A semi-compatible DSL for the Bundler Gemfile and Isolate formats.
+# A semi-compatible DSL for the Bundler Gemfile and Isolate gem dependencies
+# files.
+#
+# To work with both the Bundler Gemfile and Isolate formats this
+# implementation takes some liberties to allow compatibility with each, most
+# notably in #source.
+#
+# A basic gem dependencies file will look like the following:
+#
+# source 'https://rubygems.org'
+#
+# gem 'rails', '3.2.14a
+# gem 'devise', '~> 2.1', '>= 2.1.3'
+# gem 'cancan'
+# gem 'airbrake'
+# gem 'pg'
+#
+# RubyGems recommends saving this as gem.deps.rb over Gemfile or Isolate.
+#
+# To install the gems in this Gemfile use `gem install -g` to install it and
+# create a lockfile. The lockfile will ensure that when you make changes to
+# your gem dependencies file a minimum amount of change is made to the
+# dependencies of your gems.
+#
+# RubyGems can activate all the gems in your dependencies file at startup
+# using the RUBYGEMS_GEMDEPS environment variable or through Gem.use_gemdeps.
+# See Gem.use_gemdeps for details and warnings.
+#
+# See `gem help install` and `gem help gem_dependencies` for further details.
