I have a basic ionic app that I built and I do not use any plugins or any cordova plugins. Do I need to do anything special to be able to build the app using PhoneGap Build?
Also What folders do I need to upload with my zip? Should I upload the entire app folder?
The Phonegap Build service requires a slightly different config.xml file since you use this to reference plugins and the service adds them to your app at build time, rather than adding them yourself.
Check the docs on the website for how to write a config.xml file specifically for Phonegap Build
