+This means if your change is a bug fix, it's recommend you first make sure you can reproduce the bug. Then after making the necessary changes to fix it, test it using the same method you used to originally confirm the bug. \
+When you're opening a pull request, make sure to mention how to reproduce the bug, so that reviewers can confirm that your chance indeed fixed the issue.
+
+If your change is a new feature, make sure to test both that the newly added functionality performs as expected, as well as ensuring that it doesn't introduce any form of regression bugs. This means, testing anything that might be affected by your new feature.
