The documentation for the Telerik Verified AWS Plugin is located here
and a little bit more in depth here
. Most importantly, the docs explain that the plugin simply wraps the AWS JS SDK and you should take a look at the AWS JS SDK Documentation
to see how to use it. There are also some examples using the SDK here
. They are examples of how to use the SDK in the browser, but the code should be the same. The only difference is that in Cordova you should wait for the deviceready event and in the browser you are including the JS SDK library as a resource.
Let me know if you have further questions.
