 The [helm-controller](https://github.com/fluxcd/helm-controller) is a Kubernetes operator that allows users to declaratively manage Helm chart releases. The desired state of a Helm release is described through a Kubernetes Custom Resource named HelmRelease. Based on the creation, mutation or removal of a HelmRelease resource in the cluster, Helm actions are performed by the operator.
