If you install the plugin you get 2 countries included;
You can delete them from the settings page (if you want). And re-import them separately (if you would only need 1 or 2).
Get more countries
If you would like to get more countries for your form, you can create a CSV formatted file/data set and import them manually. Please find more info about this in the contextual help menus.
We also have some 'pre-made country packages', which are ready to be imported.
