+## ChefTap
+ChefTaps allows you to export your recipes from the app (I think). The export is a zip file containing a folder called
+`recipes` which in turn contains `.txt` files with your recipes.
+
+This format is basically completely unstructured and every export looks different. This makes importing it very hard
+and leads to suboptimal results. Images are also not supported as they are not included in the export (at least 
+the tests I had).
+
+Usually the import should recognize all ingredients and put everything else into the instructions. If you import fails
+or is worse than this feel free to provide me with more example data and I can try to improve the importer.
+
+As ChefTap cannot import these files anyway there won't be an exporter implemented in Tandoor.
