 ## Requirements
 
+Split currently requires Ruby 1.9.2 or higher. If your project requires compatibility with Ruby 1.8.x and Rails 2.3, please use v0.8.0.

 Split uses redis as a datastore.
 
 Split only supports redis 2.0 or greater.
 
 If you're on OS X, Homebrew is the simplest way to install Redis:

-If you are using Redis on Ruby 1.8.x then you will likely want to also use the SystemTimer gem if you want to make sure the Redis client will not hang.

-Put the following in your gemfile as well:

-```
-gem 'SystemTimer'

 ### Rails 3
 
 Split is autoloaded when rails starts up, as long as you've configured redis it will 'just work'.
 
-### Rails 2.3

-To configure Rails 2.3 with Split you need to mix in the helper methods. Add the following lines to config/initializers.split.rb:
-
-```ruby
-ActionController::Base.send :include, Split::Helper
-ActionController::Base.helper Split::Helper

-Note: If using ruby 1.8.x and weighted alternatives you should always pass the control alternative through as the second argument with any other alternatives as a third argument because the order of the hash is not preserved in ruby 1.8, ruby 1.9.1+ users are not affected by this bug.

 This will only show the new alternative to visitors 1 in 10 times, the default weight for an alternative is 1.
 
 ### Overriding alternatives
 
 For development and testing, you may wish to force your app to always return an alternative.

 You can even use Devise or any other Warden-based authentication method to authorize users. Just replace `mount Split::Dashboard, :at => 'split'` in `config/routes.rb` with the following:
 ```ruby
-match "/split" => Split::Dashboard, :anchor => false, :constraints => lambda { |request|
+match "/split" => Split::Dashboard, :anchor => false, :via => [:get, :post], :constraints => lambda { |request|
   request.env['warden'].authenticated? # are we authenticated?
   request.env['warden'].authenticate! # authenticate if not already
   # or even check any other condition such as request.env['warden'].user.is_admin?
 }
 ```
