+Before reporting a bug, you should try stripping down your Vim configuration
+and removing other plugins.  The sad truth about VimScript is that it is
+fraught with incompatibilities waiting to happen.  I'm happy to work around
+them where I can, but it's up to you to isolate the conflict.
+
+Fugitive is particularly prone to regressions due to Git version issues,
+platform issues, and interactions with other plugins.  I end up bisecting a
+lot more than other projects, and thus I'm especially meticulous here about
+maintaining a clean, readable, history.  Squash and force push any requested
+changes to a pull request.  And if your [commit message
+sucks](https://commit.style), I'm not going to accept it.  Period.
+
+If your contribution involves adding a configuration option, you are going to
+need a very compelling justification for it.  Options add a maintenance
+burden, support burden, and documentation bloat, and oftentimes can be
+achieved much more simply with a custom map or autocommand.  If your option
+controls an underlying Git command, ask yourself why Git itself does not offer
+such configuration.
+
+Beyond that, don't be shy about asking before patching.  What takes you hours
+might take me minutes simply because I have both domain knowledge and a
+perverse knowledge of VimScript so vast that many would consider it a symptom
+of mental illness.  On the flip side, some ideas I'll reject no matter how
+good the implementation is.  "Send a patch" is an edge case answer in my book.
