+## New Infra (v2) Overview
+
+This repo now includes a modular, best‑practice infrastructure under `infra/` to make replication and selective deployment easy. It is centered on Traefik as the reverse proxy with automatic TLS via Let's Encrypt, environment layering, and pick‑what‑you‑need application stacks.
+
+- Core: `infra/core/traefik` — Traefik with HTTPS (ACME), dashboard, and sane defaults
+- Apps: `infra/apps/<service>` — self‑contained stacks (e.g., `nextcloud`)
+- Env: `infra/env/<environment>/common.env` — environment defaults (dev/prod)
+- Secrets: `infra/secrets/` — local secret storage (ignored by git)
+- Make targets: top‑level `Makefile` to bootstrap, start proxy, and start apps
+
+Quickstart
+
+- Copy `infra/env/development/common.env` and adjust domains and ACME email.
+- Create the shared proxy network and ACME storage: `make bootstrap`
+- Start Traefik: `make proxy-up`
+- Start a service, e.g. Nextcloud: `make app-up APP=nextcloud`
+
+Notes
+
+- Traefik dashboard is exposed at `TRAEFIK_DASHBOARD_DOMAIN` with optional basic auth.
+- Services connect to an external `proxy` network for routing, plus their own internal network.
+- Each app has its own `.env.example`; copy to `.env` and adjust.
+- The legacy `apps/` structure remains as-is; new infra is additive and can coexist.
