Add a README to paranoia

README.md

+h1. Paranoia
+
+Paranoia is a re-implementation of [acts\_as\_paranoid](http://github.com/technoweenie/acts_as_paranoid) for Rails 3, using much, much, much less code.
+
+You would use either plugin / gem if you wished that when you called `destroy` on an Active Record object that it didn't actually destroy it, but just "hid" the record. Paranoia does this by setting a `deleted_at` field to the current time when you `destroy` a record, and hides it by scoping all queries on your model to only include records which do not have a `deleted_at` field.
+
+h2. Installation & Usage
+
+h3. Initial installation
+
+In your _Gemfile_:
+
+    gem 'paranoia'
+
+Then run `bundle install`
+
+Or if you're still on Rails 2:
+
+    config.gem 'paranoia'
+
+Then run `rake gems:install`
+
+h3. Usage
+
+In your model:
+
+    class Client < ActiveRecord::Base
+      acts_as_paranoid
+      
+      ...
+    end
+
+Hey presto, it's there!
