+include:
+
+* Using welcoming and inclusive language.
+* Being respectful of differing viewpoints and experiences.
+* Gracefully accepting constructive criticism.
+* Focusing on what is best for the community.
+* Showing empathy towards other community members.

+
+Before reporting a bug, please
+https://schlomp.space/tastytea/{project}/issues[perform a search] to see if the
+problem has already been reported. If it has, add a comment to the existing
+issue instead of opening a new one. Same for enhancements.

+
+You can also send me your patches via mailto:{contact-email}[E-Mail], ideally
+using `git format-patch` or `git send-email`.
