+## Docker
+
+If you have Docker installed you can build and run the application in an isolated container:
+
+```bash
+# Build image (only once)
+docker build -t swiper-app .
+
+# Run the container on port 8888
+docker run --rm -p 8888:8888 swiper-app
+```
+
+Then open [http://localhost:8888](http://localhost:8888) in your browser.
+
+The Dockerfile uses a minimal Python 3.11 image, installs the Python dependencies from `requirements.txt`, exposes port 8888 and starts the app with `python server.py`.
+
+### Docker Compose
+
+A `docker-compose.yml` file is included so you can run the container with your image folders mounted automatically.
+
+```bash
+# Build image (first time or when code changes)
+docker compose up --build
+```
+
+This will:
+
+- Publish port **8888** on your host → container.
+- Mount the portrait and landscape image folders (update paths in `docker-compose.yml` as needed) read-only into `/media/Portrait` and `/media/Landscape` inside the container.
+- Set `IMAGE_DIRS=/media/Portrait:/media/Landscape` so the server finds the images.
+
+Adjust ports, folders or environment variables by editing `docker-compose.yml`. Remember to rebuild (`docker compose up --build`) after changes.
