To add recipes from a cookbook into Shop'NCook, you need first to scan them. If your scanning utility includes an OCR function, as most do, you will be able to save to scanned file to text or pdf format. Do not select an image format as Shop'NCook will not be able to understand the recipe if you save it to this format.
Open the saved file in a text editor or pdf viewer, select the text content and copy it to the clipboard. For pdf files, you may have to select the text tool first (the button with a A on it) to be able to select the text.
Open then Shop'NCook and click on the clip button of the toolbar to import the recipe. Alternatively select "Import Recipes from Clipboard" in the File menu.
