+=About
+
+This gem provides sexy validations/ validators functionality for models. 
+It was heavily inspired by the new validators in rails 3. Basically
+it's a replacement for "inlcude ActiveModel::Validations", because those
+are strangely complex and don't work together properly with sequel for
+example.
+
+==Install
+
+Simply install it as any other gem:
+
+  gem install sexy_validations
+
+Or when using bundler, add it got your Gemfile:
+
+  gem sexy_validations
+
+This should also install the geokit gem.
+
+==Quick Start
+
+In your model:
+
+  class User
+    plugin :sexy_validations
+
+    validates :name, :presence => true, :length => 2..20
+    validates :desfription, :length => 0..2000
+    validates :photo, :image => "250x250" # see the sequel_paperclip gem
+  end
+
+==Todo
+
+* Use I18n for messages
+* Source documentation (rdoc)
+* Tests
+
+==Contributing
+
+If you'd like to contribute a feature or bugfix: Thanks! To make sure your
+fix/feature has a high chance of being included, please read the following
+guidelines:
+
+1. Fork the project.
+2. Make your feature addition or bug fix.
+3. Add tests for it. This is important so we don’t break anything in a future version unintentionally.
+4. Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
+5. Send me a pull request. Bonus points for topic branches.
