-Before opening your issue **you must check our instructions** for [reporting bugs](https://github.com/caskroom/homebrew-cask#reporting-bugs) or [making requests](https://github.com/caskroom/homebrew-cask#requests), as appropriate. Note the former has several links to help diagnose and fix common issues.
+#### General troubleshooting steps
 
-If none of those guides is appropriate, delete this template and explain your issue in detail.
+- [ ] I have checked the instructions for [reporting bugs](https://github.com/caskroom/homebrew-cask#reporting-bugs) (or [making requests](https://github.com/caskroom/homebrew-cask#requests)) before opening the issue.
+  - [ ] None of the templates was appropriate for my issue, or I’m not sure.
+- [ ] I ran `brew update-reset && brew update` and retried my command.
+- [ ] I ran `brew doctor`, fixed as many issues as possible and retried my command.
+- [ ] I understand that [if I ignore these instructions, my issue may be closed without review](https://github.com/caskroom/homebrew-cask/blob/master/doc/faq/closing_issues_without_review.md).
 
-Please note that **if it is apparent you ignored the instructions for reporting issues, we may close the issue without review**. Dealing with the same solved and documented problems leads to maintainer burnout and wasted hours. Those would be better spent improving Homebrew-Cask itself and fixing real bugs.
+#### Description of issue
 
-If the guides themselves were unclear, help us improve them! Open *first* an issue or pull request stating what you found confusing *and only then* your other issue.
