The configuration translation endpoint will help you get started with your config file. You will want to tweak the output, but it should help you get started.
You can use the command line interface to validate your config changes with a pre-commit Git hook. This will help you avoid running a bunch of failed builds while you are fine-tuning your syntax. Read how in the docs or watch this video.
