+# zROC UI
+
+**Zerto Resiliency Observation Console** — a purpose-built observability frontend for Zerto that replaces Zerto Analytics with a self-hosted, always-on dashboard.
+
+## What it does
+
+- **NOC Dashboard** — VPG health heat grid, site cards, RPO status at a glance
+- **VPG Monitor** — per-VPG RPO history, throughput/IOPS charts, journal health, VM breakdown
+- **VM Protection** — per-VM drill-down with RPO trends, journal gauges, encryption trends
+- **VRA Infrastructure** — CPU/memory usage, workload counts, volume capacity
+- **Encryption Detection** — near real-time ransomware anomaly detection
+- **Storage** — datastore capacity with Zerto-attributed journal/scratch/recovery breakdown
+- **User Management** — full CRUD with 2FA QR code setup, group management, enterprise IdP integration
+
+## Authentication
+
+This image includes a Node.js Express backend that handles:
+- OIDC login via **Authentik** (bundled in the full stack)
+- 2FA enforcement (TOTP with QR codes)
+- Enterprise IdP integration (Azure AD, Okta, SAML, LDAP)
+- Rate-limited login, `httpOnly` session cookies, zero Prometheus exposure to browser
+
+## Quick start — full stack
+
+```bash
+git clone https://github.com/ZertoPublic/zroc.git
+cd zroc
+cp .env.example .env
+# Edit .env with your ZVM credentials and secrets
+docker compose up -d
+```
+
+Then visit `https://<your-host>` — on first access run through the setup wizard.
+
