Tutorials for specific platforms


As Ionic is such easy, we find here in forum so many developers (including me) with lack of basic understanding of android, ios platforms, so, everybody stops here to ask something which is not directly related to Ionic.
I’d like to suggest some tutorials/forum for specific developments, configurations.
For example, how can I specify Android version target when running “ionic build” ? Maybe gathering all these kind of questions in specific places, could make moderator’s and developer’s life easy…

Thank you!
