+
+Hey, you've got [LiveReload](http://livereload.com/) in my [Rack](http://rack.rubyforge.org/)!
 No need for browser extensions anymore! Just plug it in your middleware stack and go!
 Even supports browsers without WebSockets!
 
 Use this with [guard-livereload](http://github.com/guard/guard-livereload) for maximum fun!
 
-## Install
-
-`gem install rack-livereload`
-
-## Using in...
+## Installation
 
 ### Rails
 
-In `config/environments/development.rb`:
+Add the gem to your Gemfile.
 
 ```ruby
+gem "rack-livereload", group: :development
+```
+
+Then add the middleware to your Rails middleware stack by editing your `config/environments/development.rb`.
+
+```ruby
+# config/environments/development.rb
+
 MyApp::Application.configure do
-  config.middleware.insert_before(Rack::Lock, Rack::LiveReload)
+  # Add Rack::LiveReload to the bottom of the middleware stack with the default options:
+  config.middleware.insert_after ActionDispatch::Static, Rack::LiveReload
 
-  # ...or, change some options...
+  # or, if you're using better_errors:
+  config.middleware.insert_before Rack::Lock, Rack::LiveReload
 
-  config.middleware.insert_before(
-    Rack::Lock, Rack::LiveReload,
-    :min_delay => 500,
-    :max_delay => 10000,
-    :port => 56789,
-    :host => 'myhost.cool.wow',
-    :ignore => [ %r{dont/modify\.html$} ]
-  )
+  # ...
 end
 ```
 
-### config.ru/Sinatra
+#### Tweaking the options
+
+```ruby
+# Specifying Rack::LiveReload options.
+config.middleware.use(Rack::LiveReload,
+  min_delay        : 500,    # default 1000
+  max_delay        : 10_000, # default 60_000
+  live_reload_port : 56789,  # default 35729
+  host             : 'myhost.cool.wow',
+  ignore           : [ %r{dont/modify\.html$} ]
+)
+```
+
+In addition, Rack::LiveReload's position within middleware stack can be
+specified by inserting it relative to an exsiting middleware via
+`insert_before` or `insert_after`. See the [Rails on Rack: Adding a
+Middleware](http://guides.rubyonrails.org/rails_on_rack.html#adding-a-middleware)
+section for more detail.
+
+### Sinatra / config.ru
 
 ``` ruby
 require 'rack-livereload'
 
 use Rack::LiveReload
 # ...or...
-use Rack::LiveReload, :min_delay => 500, ...
+use Rack::LiveReload, min_delay: 500, ...
 ```
 
 ## How it works
 
 The necessary `script` tag to bring in a copy of [livereload.js](https://github.com/livereload/livereload-js) is
-injected right before the closing `head` tag in any `text/html` pages that come through. The `script` tag is built in
+injected right after the opening `head` tag in any `text/html` pages that come through. The `script` tag is built in
 such a way that the `HTTP_HOST` is used as the LiveReload host, so you can connect from external machines (say, to
 `mycomputer:3000` instead of `localhost:3000`) and as long as the LiveReload port is accessible from the external machine,
 you'll connect and be LiveReloading away!
@@ -66,17 +91,15 @@ your browser doesn't need it. The SWF WebSocket implementor won't be loaded unle
 WebSockets support or if you force it in the middleware stack:
 
 ``` ruby
-use Rack::LiveReload, :force_swf => true
+use Rack::LiveReload, force_swf: true
 ```
 
 If you don't want any of the web-sockets-js code included at all, use the `no_swf` option:
 
 ``` ruby
-use Rack::LiveReload, :no_swf => true
+use Rack::LiveReload, no_swf: true
 ```
 
 Once more browsers support WebSockets than don't, this option will be reversed and you'll have
 to explicitly include the Flash shim.
