I am new in Office add-in development and little bit confused about creation JS plug-ins for Outlook. Actually we can create one add-in which will be available on all platforms: Outlook on Mac/PC, Outlook.com and Outlook 365.
But what about tools for it? According Outlook development [documentation](https://dev.outlook.com/MailAppsGettingStarted/GetStarted/outlook-dot-com), we can use *Yeoman* generator for creating Office add-ins. However in my VisualStudio Community 2015 is type of project like "Web add-in", where I can chose Outlook add-in. So is there some difference between *Yeoman* generator and VisualStudio Web add-in projects?
