Instructions for use? – PirateWalla Review

I love the concept of this app. However, I see no way to preview the functionality before the five dollar payout. The app opens. There is a map with a big red x. An icon says dig, but it is not activated. No marked locations or anything relating to Wallabee are visible. Instructions or at least an intro on start up the first time would be very helpful.
