Within this directory you can place custom directories for your environments and statevalues yamls.
You don't have to place them here, but this directory is a convenient place to drop them as it is relative from the root of the helmfile-deploy project and nothing in here will ever be committed.
You will need to declare some ENVIRONMENT variables pointing to the custom configuration locations within this directory for helmfile-deploy.
Note that currently these locations referred to by the following variables must be RELATIVE from the root of the helmfile-deploy project (see 743)
This variable designates where your custom helmfile state values can be found. Within this directory you can have one or more custom *.yaml that override and customize known helmfile-deploy state values defined in statevalues/ Its important to note that these values are not helm chart values, but rather values that are consumed by the helmfile release templates themselves (deployments.helmfile.yaml & conduits.helmfile.yaml)
export HELMFILE_DEPLOY_STATE_VALUES_DIR=custom-configs/[pathOfYourStateValuesDir]
This variable designates where your custom helmfile environments can be found. This directory should declare a single index.yaml that declares your helmfile environments: block. For the purposes of the helmfile-deploy framework, each helmfile environment represents a target application that can be deployed.
export HELMFILE_DEPLOY_ENVIRONMENTS_DIR=custom-configs/[pathOfYourEnvironmentsDir]
