If there’s a checkbox you can’t complete for any reason, that's okay, just explain in detail why you weren’t able to do so.

After making all changes to the cask:

• brew cask audit --download {{cask_file}} is error-free.
• brew cask style --fix {{cask_file}} reports no offenses.
• The commit message includes the cask’s name and version.
