 ruote 2.1 extension for DataMapper (dm) persistence
 
 
 == usage
 
-well...
+This is how a ruote engine is setup with a ruote-dm storage (postgres) and a worker :
+
+  require 'rubygems'
+  require 'json' # gem install json
+  require 'ruote'
+  require 'ruote-dm' # gem install ruote-dm
+  
+  #DataMapper.setup(:default, 'sqlite3::memory:')
+  #DataMapper.setup(:default, 'sqlite3:ruote_test.db')
+  DataMapper.setup(:default, 'postgres://localhost/ruote_test')
+  
+  engine = Ruote::Engine.new(
+    Ruote::Worker.new(
+      Ruote::Dm::DmStorage.new(:default)))
+
+  # ...
+
+To create the tables in the database :
+
+  Ruote::Dm::Document.auto_migrate!
+
+
+Tested with dm 0.9.2 and dm 1.0.0, with the postgresql and the msyql adapters.
