+      For the best results, please:
+        - Avoid submitting duplicates. Search first to see if it's been reported previously.
+        - Check if the issue persists with a build from the latest source.
+        - Provide all relevant information in the initial report, to prevent unnecessary back and forth discussion.
+        - If you can, try to diagnose and/or fix the issue yourself. We welcome high quality contributions.

+      Please provide a clear and concise description of what the bug is.
+
+      If relevant, add a [minimal complete example](https://stackoverflow.com/help/minimal-reproducible-example) that reproduces the bug. It is very important for the snippet to be as simple as possible, so please take time to trim down any irrelevant code to help us debug efficiently. We are going to copy-paste your code and we expect to get the same result as you did, so include both the kernel and launching code as well as any relevant imports.

+      If the code is too long (hopefully, it isn't), feel free to put it in a public gist and link it in the issue: https://gist.github.com.
