# Setup

Once you have the app installed, you can go to `Catalog > Products` and click on the product you want to edit. Then click on the `Specifications` tab and scroll down to `Custom fields.` Here you will find a custom field set called `"Nutrition labeling".`

Now activate the Nutrition Labeling for your product and determine whether your information refers to a unit or to 100 grams. Now simply enter the Nutri-Score and how many grams of each nutritional value are given for your product.

### Nutritional value needed that is not present in the list?

If you are looking for a nutritional value that you cannot find in the list, you can find it under `Additional Information` at the very end of the list.

### Enter allergens

You will find fields for the different allergen ingredients and can determine their content by simply selecting `Yes` or `No`.
