 ### Strategy classes
 
+Each strategy class can inherit from DatabaseCleaner::Strategy to get it most of the way there. If you do, you only need to define one method!
+
 Each strategy **must** have the following instance methods
   *  `#clean` -- where the cleaning happens
 
 Optionally, depending on how your strategy works you may define
-  *  `#start` -- if your strategy is transactional, this is where you would start the database transaction that `#clean` later rolls back. This method might be included with `::DatabaseCleaner::Generic::Truncation` or `::DatabaseCleaner::Generic::Transaction`
+  *  `#start` -- if your strategy is transactional, this is where you would start the database transaction that `#clean` later rolls back.
 
 Given that we're creating a strategy for truncation, you may end up with something like the following class:
 
 ```ruby
+# lib/database_cleaner/orm_name/truncation.rb
+
+require 'database_cleaner/strategy'
+require 'orm'
+
 module DatabaseCleaner
   module OrmName
-    class Truncation
