Tip: As I inferred above, many topics are covered by blogs/tutorials.
I know they are sometimes hard to find, but this usually works for me:
Google: <topic words> corona sdk blog
I am not admonishing you here. I’m giving advice I use all the time. The trick is to include a few words related to your question PLUS these words “corona sdk blog”. I think folks simply overlook this as a self-help option.
That often turns up exactly the topic I’m looking for.
Ex: _ corona sdk ads tutorial blog _ turned up the above tutorial link as the second entry:
https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=corona%20sdk%20ads%20tutorial%20blog
