 Paprika can create two types of export. The first is a proprietary `.paprikarecipes` file in some kind of binarized format.
 The second one is HTML files containing at least a bit of microdata.
 
-If you want to import your Paprika recipes create a html export. Then import the individual recipes HTML files.
-Due to the lack of structure not all fields can be imported. 
-Even tough images are present in the export they cannot be imported atm. This is technically possible and might be 
-added in the future.
+If you want to import your Paprika recipes follow these steps
+
+1. create a html export
+2. Create a `.zip` file from the `Recipes` folder (next to the `index.html`) the structure should look like this
