+    Hi there,
+
+    Please stick to one topic/question per Discussion. Start a new discussion per topic.
+
+    This prevents future users from finding this discussion and getting confused by multiple questions and answers. One question and answer per Discussion works best.
+
+    For example:
+     - Don't create a discussion with multiple questions requiring multiple answers
+     - If you got an answer to your first question, don't change topic like "Can I also ask you how I might..." which would then require a different answer. Mark the current discussion as answered and open a new one.

+    Hi there,
+
+    Please do not unnecessarily `@` mention maintainers like `@rarkins` or `@viceice`. Doing so causes annoying notifications and makes it harder to maintain this repository.
+
+    For example, never `@` mention a maintainer when you are creating a discussion if your desire is to get attention. This is rude behavior, just like shouting out your coffee order in a Starbucks before it's your turn.
+
+    It's OK to comment in an issue or discussion after multiple days or weeks. But please, still don't `@` mention people. The maintainers try to answer most discussions, but they can't answer all discussions. If you're still not getting an answer, take a look at the information you've given us and see if you can improve it.
