Require some basic build and automation info

I want to create a new settings api so that I can use it in the terraform, but I am struggling on how to move forward with this. I did try to figure out the usage of the swagger-generator and tried related configs but I had some issues like
The incoming YAML document exceeds the limit then I tried converting the yaml to json and run it based on the issue and it ran with the swagger generator, but then it generated files and doc but with the package as swagger, but then I tried adding the api-package and model-package variable in the command, but still that did not worked as expected.

The expectation here is that can someone please provide some guideline on how to refer the harness APIs, what command to use and what are the pre-requisites to be able to contribute to this repo and use it in diff use cases.
