+## Docker / Podman
+
+If you are using Podman, please pay attention in the [docker-compose.yml](./docker-compose.example.yml) example
+file that has been provided, there's comments in regards to differences between the two.
+
+
+When it comes to building the image, please make sure that you basically set the `--format docker` in the podman
+build command, otherwise it won't have HealthChecks and other issues might arise.
+
+Tip: Put the following in `~/.config/containers/containers.conf`
+```toml
+[engine]
+image_default_format = "docker"
+```
+
+For just running the docker-compose.yml with docker image format:
+```bash
+BUILDAH_FORMAT=docker podman compose up --build
+```
