+## Docker/Podman Setup
+
+The repository contains a `Dockerfile` and a `docker-compose.yml`, which will
+install all dependencies and setup the required PostgreSQL database.
+
+With Docker, this should be usable with:
+
+```bash
+docker compose -f ./docker-compose.yml up
+```
+
+For Podman users, podman-compose is needed:
+
+```bash
+pip3 install podman-compose  # if not already available
+podman-compose up
+```
+
