How to add kinesis firehose/s3 as destination in serverless.yml

Hi, I am trying to use serverless, Kinesis and Kinesis firehose to process streaming data and save to aws locations. I have successfully setup Kinesis consumer part, and data parsing through Lambda handler. I have setup Kinesis firehose and destination s3 bucket on aws, but blocked on how to configure Kinesis firehose stream as a destination on serverless.yml for data in Kinesis stream.

In short, I have two work streams, and blocked on #2.
#1) data -> kinesis stream -> lambda (parsing data) -> alternate location
#2) data -> kinesis stream -> kinesis firehose -> s3

Thank you for your time!
