To get the most out of this book

1. In the book, I assume that you have some knowledge of Angular. Most of the time the problem that you will face will be regarding Angular instead of Ionic. https://angular.io is your best friend in that case.
2. If you want to brush up your information about Angular, I would suggest this book by Victor Savkin and Jeff Cross (former Angular team members) https://www.packtpub.com/application-development/essential-angular.
3. Even though you can run most of examples without installing platform SDKs for Android or iOS. I suggest you to do this in the very beginning, in order to test the applications on actual devices. Take a look at these guides:
   • Android: https://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html#requirements-and-support 
   • iOS: https://cordova.apache.org/docs/en/latest/guide/platforms/ios/index.html
