+If the `RACK_ENV` environment variable is set, it will override this value. It should be noted that using `RACK_ENV` is the **recommended** way to set the environment, as it is a standard convention in Rack-based applications. You should just omit the `environment` key in your `hooks.yaml` file if you want to use `RACK_ENV`. The `RACK_ENV` variable is automatically set to `production` if it is not defined. It also controls the environment for the puma server and the Hooks application so that they are consistent.

+**TL;DR**: If you want to use `RACK_ENV`, just don't set the `environment` key in your `hooks.yaml` file. Plus you should really just use `RACK_ENV` anyway, as it is the standard way to set the environment in Rack-based applications.
