 Automatically userstamps create and update operations if the table has fields named created_by and/or updated_by.
 
+Blame adds a `userstamps` migration helper which will create both created_by and updated_by columns to your table:
+
+      create_table :widgets do |t|
+        t.string :name
+        t.timestamps
+        t.userstamps
+      end
+
 Blame defaults to looking for the current user in User.current_user, but you can override this behavior by writing your own userstamp_object method in ActiveRecord::Base or any of your models:
 
-  def userstamp_object
-    User.current_user # the default
-    Superduper.superman
-  end
+      def userstamp_object
+        User.current_user # the default
+        Superduper.superman
+      end
 
 Automatic userstamping can be turned off by setting
-  <tt>ActiveRecord::Base.record_userstamps = false</tt>
+
+    ActiveRecord::Base.record_userstamps = false
+
+
