It's easy to add a country to your list. Go to your "Contacts" and open the dossier of any of your clients. Scroll all the way down in the "Country" menu, then choose "Countries..."
In the next window, click the blue plus button.
Then, add some parameters to the country. In our example, we're adding Luxembourg to our list of countries.
If you're using several languages, translate the name of the country by clicking the blue dictionary button.
