Insufficient Documentation

[infobrixGit]

Please can you add more documentation
@BlobTrigger(name = "triggerBlob", path = "test-triggerinput-java/{name}", dataType = "binary") byte[] triggerBlob,
@BindingName("name") String fileName,
@BlobInput(name = "inputBlob", path = "test-input-java/{name}", dataType = "binary") byte[] inputBlob,
@BlobOutput(name = "outputBlob", path = "test-output-java/{name}", dataType = "binary") OutputBinding<byte[]> outputBlob,
final ExecutionContext context

How to use that code ? If triggerBlob = content , then what is inputBlob? what is the goal ?
Please explain/ document every argument , every annotation , every configuration to be created or this code assumes and purpose
