+== Creating the test database
+
+The default name for the test databases is "activerecord_versioned". If you 
+want to use another database name then be sure to update the connection 
+adapter setups you want to test with in test/connections/<your database>/connection.rb. 
+When you have the database online, you can import the fixture tables with 
+the test/fixtures/db_definitions/*.sql files.
+
+Make sure that you create database objects with the same user that you specified in i
+connection.rb otherwise (on Postgres, at least) tests for default values will fail.
+
+== Running with Rake
+
+The easiest way to run the unit tests is through Rake. The default task runs
+the entire test suite for all the adapters. You can also run the suite on just
+one adapter by using the tasks test_mysql_ruby, test_ruby_mysql, test_sqlite, 
+or test_postresql. For more information, checkout the full array of rake tasks with "rake -T"
+
+Rake can be found at http://rake.rubyforge.org
+
+== Running by hand
+
+Unit tests are located in test directory. If you only want to run a single test suite, 
+or don't want to bother with Rake, you can do so with something like:
+
+   cd test; ruby -I "connections/native_mysql" base_test.rb
+   
+That'll run the base suite using the MySQL-Ruby adapter. Change the adapter
+and test suite name as needed.
+
+== Faster tests
+
+If you are using a database that supports transactions, you can set the
+"AR_TX_FIXTURES" environment variable to "yes" to use transactional fixtures.
+This gives a very large speed boost. With rake:
+
+  rake AR_TX_FIXTURES=yes
+
+Or, by hand:
+
+  AR_TX_FIXTURES=yes ruby -I connections/native_sqlite3 base_test.rb

+        # * <tt>inheritance_column</tt> - name of the column to save the model's inheritance_column value for STI.  (default: versioned_type)
+        # * <tt>version_column</tt> - name of the column in the model that keeps the version number (default: version)

+        # contain all the fields you want versioned, the same version column, and a #{model}_id foreign key field.
+        #
+        # A lock_version field is also accepted if your model uses Optimistic Locking.  If your table uses Single Table inheritance,
+        # then that field is reflected in the versioned model as 'versioned_type' by default.
+        #
+        # Acts_as_versioned comes prepared with the ActiveRecord::Acts::Versioned::ActMethods::ClassMethods#create_versioned_table
