A step of the [Cloud application](https://gradus.kazet.blog/tree/cloud-application) tree on Gradus, in the Build & ship area: Config, lint, releases, IaC.

Establish a conventional folder structure and a config module that validates environment variables at startup, so new code has an obvious home and a bad deploy fails fast.

Usually comes after: [Continuous integration](https://gradus.kazet.blog/tree/cloud-application/step/ci-pipeline).

Leads to: [Linting & formatting](https://gradus.kazet.blog/tree/cloud-application/step/lint-and-format), [Infrastructure as code](https://gradus.kazet.blog/tree/cloud-application/step/infrastructure-as-code).
