+Hi there!
+
+### The issue tracker is for "issues", the openFrameworks forum is for "questions".
+
+What is the difference? A obvious question might be "How do I get openFrameworks to compile on Android?" An obvious issue might be "The function `ofRandom()` always returns the number 42 on Linux Ubuntu 16.04".
+
+Before you submit an issue, make sure:
+
+* You are certain that the expected result and the actual result _are different_.
+* You have code to demonstrate it. If you aren't certain what the "expected" result is (due to poor documentation), then please first ask about it on the forum https://forum.openframeworks.cc. There's a good chance there's a real issue, but please post it on the forum if you are in doubt.
+* You searched the issue tracker and no one submitted this issue before.
+* For issues with the openFrameworks website, go to https://github.com/openframeworks/ofSite/issues
+* For issues with the ProjectGenerator, go to https://github.com/openframeworks/projectGenerator/issues
