+= Radiant Validators
+
+This [Radiant CMS][1] extension allows extension developers to easily override the validators built into Radiant's models. This is done 
+by adding new functions to the ActiveRecord class to clear validations, and remove validations based on a name. All built-in Radiant 
+model validations are cleared and redefined in this extension with names set to allow other extensions to remove them easily.
+
+= INSTALLATION
+
+1: Install the extension files
+
+  Automated Installation:
+  ./script/extension install radiant_validators
+
+  Manual Installation:
+  cd ./vendor/extensions
+  git clone git://github.com/JediFreeman/Radiant-Validators-Extension.git
+
+2: Restart the server
+
+= HOW TO USE
+
+To override a validator, it is pretty straight forward. Take a look at the example below that overrides the Page model slug format 
+validator to allow apostrophes.
+
+1: In your extension lib directory, create an extender file for the model you wish to override (for example, to override the Page model, 
+create page_extender.rb) and add the following:
+
+module PageExtender
+  def self.included(base)
+    base.class_eval {
+      # remove the existing validation for slug format
+      base.remove_validation :page_slug_format
+
+      # add a new validator with a slightly different regex to allow apostrophes
+      validates_format_of :slug, :with => %r{^([-_.A-Za-z0-9']*|/)$}, :message => 'invalid format', :name => :page_slug_format
+    }
+  end
+end
+
+2: In your main extension file activate method, include your extender on the Page model:
+
+def activate
+  Page.send :include, PageExtender
+end
+
+3: Restart the server
+
+= ADDITIONAL INFORMATION
+
+To see a list of validator names, take a look in radiant_validators/app/models/*_validation_extender.rb files.
+
+custom validator functions (defined with 'validate :function_name') are not in the scope of this extension, as those can already easily 
+be overridden by creating a new function in your extender.
+
+You can verify the validators on a model by loading up the script/console and calling <Model>.validate (ie, Page.validate). You will get a list of validators and you should be able to see the :name setting for each one.
