 Add this line to your application's Gemfile:
 
     gem 'rails-sandbox-assets'
 
+Or if you prefer to use the master branch:
+
+    gem 'rails-sandbox-assets', git: 'git://github.com/rosenfeld/rails-sandbox-assets' # or:
+    gem 'rails-sandbox-assets', github: 'rosenfeld/rails-sandbox-assets' # Bundler-pre syntax
+
 And then execute:
 
     $ bundle
 
 ## Usage
 
+Place your tests under _test/javascripts/\*\_test.js_ or _specs/javascripts/\*\_spec.js.coffee_.
+Use JavaScript or CoffeeScript.
+
+You can add your test assets to _test/assets/javascripts_, _test/assets/stylesheets_,.
+_specs/assets/javascripts_ and _specs/assets/stylesheets_.
+
     $ rake sandbox_assets:serve
 
 Follow the instructions in http://localhost:5000 for how to override the void bundled test-runner.
 
+You can run a subset of your tests by specifying a path like _http://localhost:5000/products_.
+
+This will only run your tests which path starts with _test/javascripts/products_, for example.
+
 ## Settings
 
-TODO: Talk about the engine config options
+You can change your settings directly from config/application.rb, if you want to:
+
+    config.sandbox_assets.template = 'spec_runner/runner'
+
+By default this setting is nil, which will follow the Rails convention and use
+_app/views/sandbox_assets/test_runner/index.html.erb_. You could actually use HAML if you prefer.
+
+Just create such file in your application to override the default one. With the option in the
+example above, you should create your view in _app/views/spec_runner/runner.html.erb_.
+
+Or you can create a separate initializer if you prefer:
+
+    # config/initializers/setup_sandbox_assets.rb
+    SandboxAssets::Engine.config.sandbox_assets.tap do |c|
+      c.template = 'test_runner/index' # set the runner template path
+      c.disable_template_param = true
+    end
+
+Default settings:
+
+    c.port = 5000
+    # By default, sandbox_assets will look for your tests in test/javascripts and specs/javascripts
+    c.tests_roots = %w(test/javascripts specs/javascripts)
+    # Add to Rails assets path. Besides your tests/specs, any assets in those paths will be served
+    # by the asset pipeline:
+    c.assets_paths = c.tests_roots + 
+        %w(test/assets/javascripts  test/assets/stylesheets
+          specs/assets/javascripts specs/assets/stylesheets)
+    # Pattern to find your tests or specs inside the tests_roots directories:
+    c.tests_patterns = %w(**/*_{test,spec}.{js,coffee}*)
+    # By default, you can override which template to use in the params, like:
+    # http://localhost:5000/?template=spec_runner/runner
+    c.disable_template_param = false
 
 ## Examples
 
 TODO: Add some examples, like Jasmine and Mocha/Chai.js.
