+Thanks for your interest in contributing to git-crypt!  git-crypt is
+open source software and welcomes contributions in the form of code,
+documentation, bug reports, or anything else that improves git-crypt.
+
+When contributing code, please consider the following guidelines:
+
+ * You are encouraged to open an issue on GitHub or send mail to
+   git-crypt-discuss@lists.cloudmutt.com to discuss any non-trivial
+   changes before you start coding.
+
+ * Please mimic the existing code style as much as possible.  In
+   particular, please indent code using tab characters with a width
+   of 8.
+
+ * To minimize merge commits, please rebase your changes before opening
+   a pull request.
+
+ * To submit your patch, open a pull request on GitHub or send a
+   properly-formatted patch to git-crypt-discuss@lists.cloudmutt.com.
+
+Finally, be aware that since git-crypt is security-sensitive software,
+the bar for contributions is higher than average.  Please don't be
+discouraged by this, but be prepared for patches to possibly go through
+several rounds of feedback and improvement before being accepted.
+Your patience and understanding is appreciated.
