+As i only had limited sample data feel free to open an issue if your RezKonv export cannot be imported.
+
+## OpenEats
+OpenEats does not provide any way to export the data using the interface. Luckily it is relatively easy to export it from the command line.
+You need to run the command `python manage.py dumpdata recipe ingredient` inside of the application api container.
+If you followed the default installation method you can use the following command `docker-compose -f docker-prod.yml run --rm --entrypoint 'sh' api ./manage.py dumpdata recipe ingredient`.
+
+Store the outputted json string in a `.json` file and simply import it using the importer. The file should look something like this
+```json
+[
+   {
+      "model":"recipe.recipe",
+      "pk":1,
+      "fields":{
+         "title":"Tasty Chili",
