## TL;DR

Helm (Deis, 2015, graduated CNCF) is the Kubernetes package manager — 'apt/yum for K8s'. Charts package Kubernetes resources (Deployments, Services, ConfigMaps) with templating (Go templates) and values. Helm 3 (2019) removed Tiller (server component) for improved security.

## Core Explanation

Chart structure: `Chart.yaml` (metadata), `values.yaml` (defaults), `templates/` (Kubernetes YAML with Go templates). `helm install myapp ./chart --set image.tag=v2`. `helm upgrade` for rolling updates. Repositories: `helm repo add stable https://charts.helm.sh/stable`. Helmfile: declarative Helm chart management. Hooks: pre/post install/upgrade/delete.
