+Simple API plugin to serving data from Q2A script in JSON.
+
+## Installation

+**Important notice about code!**
+This code don't respect PHP PSR-2 standard, because Question2Answer unfortunately too don't respect this. Also, I couldn't design classes and functions in my own way, because most of them impose Question2Answer script.
