+### Post questions on StackOverflow not GitHub
+
+If you have a question or need help with a specific topic, please search for an answer on StackOverflow first. If you can't find the answer than please post your question on StackOverflow. If you don't get an answer on StackOverflow after a few days, feel free to create a ticket with a link to the StackOverflow question. Our preference is to keep GitHub issues for bug reports or new feature and enhancement requests.
