  === Submitting an Issue
  
  We use the {issues}[issue tracker on GitHub] associated with this project to track bugs and features.
  Before submitting a bug report or feature request, check to make sure it hasn't already been submitted.
  When submitting a bug report, please include a {gist}[Gist] that includes any details that may help reproduce the bug, including your gem version, Ruby version, and operating system.
  
  Most importantly, since Asciidoctor is a text processor, reproducing most bugs requires that we have some snippet of text on which Asciidoctor exhibits the bad behavior.
