+### Conditional encrypting ###
+
+There may be times that you want to only encrypt when certain conditions are met. For example maybe you're using rails and you don't want to encrypt 
+attributes when you're in development mode. You can specify conditions like this:
+
+	class User
+	  attr_encrypted :email, :key => 'a secret key', :unless => Rails.env.development?
+	end
+
+You can specify both `:if` and `:unless` options. If you pass a symbol representing an instance method then the result of the method will be evaluated. 
+Any objects that respond to :call are evaluated as well.
+
+
 ### Custom encryptor ###
 
 The [Huberry::Encryptor](http://github.com/shuber/encryptor) class is used by default. You may use your own custom encryptor by specifying
 the `:encryptor`, `:encrypt_method`, and `:decrypt_method` options
