+### With Teron L-PFR Mock (Fiscalization Testing)
+
+The `Fisk/` directory contains a Python mock server that simulates a [Teron](https://teron.rs) L-PFR fiscal device (port 4566). It implements the Teron HTTP API — invoice signing, PDV calculation, QR code generation, and per-type counters — without requiring real hardware or a certificate.
+
+Use it alongside NTech for fiscalization development and testing:
+
+```yaml
+# docker-compose.yml
+services:
+  ntech:
+    image: ghcr.io/dalibor31/ntech:latest
+    container_name: ntech
+    restart: unless-stopped
+    ports:
+      - "8000:8000"
+    environment:
+      NTECH_ENV: production
+      NTECH_PORT: "8000"
+      NTECH_SQLITE: /app/data/ntech.db
+    volumes:
+      - ./data:/app/data
+      - ./uploads:/app/web/static/uploads
+      - ./logs:/var/log/ntech
+      - ./backups:/app/backups
+    networks:
+      - ntech-net
+
+  teron-mock:
+    image: ghcr.io/dalibor31/ntech-fisk:latest
+    container_name: teron_mock
+    restart: unless-stopped
+    volumes:
+      - teron-data:/app/data
+    networks:
+      - ntech-net
+
+volumes:
+  teron-data:
+
+networks:
+  ntech-net:
+```
+
+The `teron-mock` service is reachable from `ntech` at `http://teron-mock:4566` over the internal Docker network — the port is not exposed to the host.
+
+To run the mock server locally (without Docker):
+
+```bash
+cd Fisk
+pip install -r requirements.txt
+python server.py
+# or: ./start.sh
+```

+
+Folder `Fisk/` sadrži Python mock server koji simulira [Teron](https://teron.rs) L-PFR fiskalni uređaj (port 4566). Implementira Teron HTTP API — potpisivanje računa, PDV obračun, generisanje QR koda i brojače po tipu računa — bez potrebe za pravim hardverom ili sertifikatom.
+
+Koristi se uz NTech za razvoj i testiranje fiskalizacije:
+
+```yaml
+# docker-compose.yml
+services:
+  ntech:
+    image: ghcr.io/dalibor31/ntech:latest

+
+Servis `teron-mock` je dostupan iz `ntech` kontejnera na adresi `http://teron-mock:4566` preko interne Docker mreže — port nije izložen spolja.
+
+Za lokalno pokretanje moka (bez Dockera):
