At the time the original issue template was created, GitHub always displayed a reminder to read CONTRIBUTING.md with a link above the new issue creation field. Unfortunately, this has since been changed so that a reminder is now shown on the right side of the field only for new contributors or if CONTRIBUTING.md has changed since the user's last contribution, and a less prominent link to the right otherwise.
GitHub's note to read CONTRIBUTING.md during the issue creation process is a bit too easy to ignore. The text of the ISSUE_TEMPLATE.md file is added directly to the issue body text input field, making this note impossible to miss. It is hoped this will increase compliance with the Contributing Rules.
