+
+### Transfer the image to another machine
+
+If you intent to run the container on a different machine, either upload it to a registry of your choice or save it as a tar-file and copy it as needed. If you intent to upload it to a registry, make sure you name it accordingly, e.g. docker.example.com/flutter-pwa-test:latest.
+
+```bash
+docker push <image-name>
+```
+
+```bash
+docker save -o <file-name>.tar <image-name>
+```
+
+To import the tar-file on another machine:
+
+```bash
+docker load -i <file-name>.tar
+```
+
+### Run the image
+
+You can either run the image from the cli or using docker compose:
+
+```bash
+docker run --rm -p 5000:80 --restart unless-stopped --name flutter-pwa-test <image-name>
+```
+
+Assuming you are in the root of the project containing the `docker-compose.yml` file. Otherwise specify the file using the `-f` flag.
+
+```bash
+docker-compose up -d
+```
