If you have ri (or fastri or qri installed), you've got a good basic 
intro. Here's the example from running 'ri YAML':

          require "yaml"

          test_obj = ["dogs", "cats", "badgers"]

          yaml_obj = YAML::dump( test_obj )
                              # -> ---
                                   - dogs
                                   - cats
                                   - badgers
          ruby_obj = YAML::load( yaml_obj )
                              # => ["dogs", "cats", "badgers"]
          ruby_obj == test_obj
                              # => true

See also YAML.load and YAML.dump in the ri docs.
