 Helm 3.19 may return empty content for `.Files.Get` on Windows; this chart uses `fromYaml (.Files.AsConfig)` as a workaround so packaged files still render correctly.
 
+## Ingress (web UI)
+
+Enable `ingress.enabled` and set `ingress.host` (and optional TLS). Traffic is sent to Service **`revproxy`** (internal nginx). On k3s, `ingress.className: traefik` matches the default controller.

 ## Not migrated in this chart
 
-- **Edge proxy stack** (`app/proxy/docker-compose.yml`, host 80/443) — use k3s **Traefik** / **Ingress** + **cert-manager**, or a separate DaemonSet/nginx chart.
+- **Edge proxy stack** (`app/proxy/docker-compose.yml`, host 80/443 Swarm mode) — replaced for K8s by this **Ingress** + `revproxy`; optional **cert-manager** for TLS at the Ingress.
 - **Swarm-only secrets** (e.g. `ssl_passphrase`) — handle via Kubernetes Secrets or external operators.
