Title: Update PORO description

It's not entirely clear how `read_attribute_for_serialization` is supposed to be implemented. I had to look back at the older README to find the mention of `ActiveModel::SerializerSupport`.

```ruby
class Poro
include ActiveModel::SerializerSupport

# ...
end
```

Is there a better way to handle this?
