+
+    2. It never hurts to state which commit or release tag you are using in case
+       the question is about build issues.
+
+    3. Try to use GitHub markdown formatting to make your issue more readable:
+         https://help.github.com/en/github/writing-on-github/basic-writing-and-formatting-syntax#quoting-code
+
+    4. Try to search for the issue before posting the question:
+         -> Issues tab -> Filters
+
+    5. Check the FAQ before posting a question:
