+## Docker install
+
+1. Create a `docker-compose.yml`:
+
+    ```yaml
+    version: "3.9"
+
+    services:
+      db:
+        image: postgres:16
+        container_name: photo26-db
+        restart: unless-stopped
+        environment:
+          POSTGRES_DB: photo26
+          POSTGRES_USER: photo26
+          POSTGRES_PASSWORD: change-me
+        volumes:
+          - ./postgres_data:/var/lib/postgresql/data
+
+      photo26:
+        image: git.sinfonie.org/sinfonie/photo26:latest
+        container_name: photo26-app

+          - db
+        environment:
+          DB_ENGINE: postgres
+          DB_NAME: photo26
+          DB_USER: photo26
+          DB_PASSWORD: change-me
+          DB_HOST: db
+          DB_PORT: 5432
+          SECRET_KEY: change-me
+          EXTRA_HOSTS: photos.example.org
+        volumes:
+          - ./static:/app/static
+          - ./media:/app/media
+        ports:
+          - "8080:8000"
+    ```
+
+2. Start the stack:
+
+    ```bash
+    docker compose up -d
+    ```
+
+    On first start the container will run migrations and create a default admin account automatically.
+
+3. **Default credentials** — change these immediately after first login:
+
+    | Field    | Value           |
+    |----------|-----------------|
+    | Username | `admin`         |
+    | Password | `admin`         |
+    | Email    | `admin@localhost` |
+
+    Admin panel: `http://localhost:8080/admin/`
+
+4. **Passwords to change** in `docker-compose.yml` before going to production:
+    - `POSTGRES_PASSWORD` / `DB_PASSWORD` — database password
+    - `SECRET_KEY` — Django secret key (use a long random string)
+    - Log in to the admin panel and change the `admin` user password
