aws sdk for php 2 integration with codeigniter

[eluser]Unknown[/eluser]
Hello. I am having some problems with getting the aws sdk2 for php to work in my codeigniter installation. Basically, I dont know where to begin! The old aws sdk was pretty simple to integrate, you had the main sdk class and the config file, and there were plenty of resources on google for implementing it. But I cant find anything similar for this new sdk and it looks more complicated than the first sdk. Can anyone help me get started or point me to a resource I may have missed? The features of the sdk I am particularly interested in are dynamodb and s3. Thanks.
