How can I use async/await in my node v6.10.3 LTS code

I want to use async/await in my node v6.10.3 LTS code for AWS Lambda. However, from what I was reading, Node comes with bundles async/await support from v7.6.0.

How can I go about integrating async await in my code so that when the node version on lambda is upgraded, I would not have to make much(if any) changes.
