 ## Motivation
 When I visited [here ](http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html#query-property
-) for the first time, I closed this page in a moment.
-Because it is too long and hard to see to understand. Especially people who are not in English-speaking world.
-After that I decided to not involve with DynamoDB at Node.js Project.
-But After a while, Fortunately or unfortunately I faced time to use DynamoDB with Node.js again and There was no escape way.
-So I decided to develop client to handle it more easier and It doesn't take waste of time to read documentation.
-Now I think this opportunity is chance to be good friend with it.  
-My fighting has started.
