Root URL: The root URL must point to the url of the site with no folders specified, e.g www.example.com do not add a trailing slash
Folder Path: If the script is stored in a sub folder, specify the path, e.g myscripts/crawler with no trailing slash
Item Sub Folder: As a default setting, all items are placed in a sub directory named 'articles'. However, we realise this may not be applicable to all sites, for example, if the feeds you're aggregating are for products, you might wish to change the item sub folder to 'products'
