+If you find a bug in cairo we would love to hear about it. We're also
+trying to make cairo better, and learning about the bugs that users
+encounter is an essential part of that. So we really appreciate the
+extra effort users put in to providing high-quality bug reports.
+
+There are two acceptable ways to report cairo bugs, and you can choose
+which you prefer:
+
+1) Bugzilla bug tracking database:
+
+ You can use the following web interface to report new bugs, follow
+ up on previous bug reports, and search for existing, known
+ bugs. Just use the "cairo" product:
+
+ https://bugs.freedesktop.org
+
+ It is necessary to go through a quick account creation process,
+ (with email address verification), in order to be able to report
+ new bugs in bugzilla. We apologize for any inconvenience that might
+ cause, and hope it won't prevent you from reporting bugs.
+
+2) Cairo mailing list:
+
+ For people who cannot stand the bugzilla interface, you can just
+ send an email to cairo mailing list (cairo@cairographics.org). The
+ mailing list only allows posting from subscribers, so use the
+ following page for subscription instructions:
+
+ https://cairographics.org/lists
+
+ Again, we apologize for any inconvenience this subscription step
+ might cause, but we've found it necessary to require this in order
+ to enjoy spam-free discussions on the list.
+
+ If you don't actually _want_ to be a subscriber to the mailing
+ list, but just want to be able to send a message, the easiest thing
+ to do is to go through the subscription process, and then use the
+ preferences page to disable message delivery to your address.
+
+Which of the above you use to report bugs depends on your own
+preferences. Some people find just typing an email message much easier
+than using the web-based forms on bugzilla. Others greatly prefer the
+ability to check back on a specific bug entry in bugzilla without
+having to ask on the mailing list if an issue has been resolved.
+
+Regardless of which method you use, here are some general tips that
+will help you improve the quality of your bug report, (which will help
+in getting the bug fixed sooner):
+
+1) Check to see if the bug has been reported already. It's pretty easy
+ to run a search or two against the cairo product in the
+ https://bugs.freedesktop.org bugzilla database. Another place to
+ look for known bugs is the cairo ROADMAP:
+
+ https://cairographics.org/ROADMAP
+
+ which shows a planned schedule of releases and which bug fixes are
+ being planned for each release.
+
+2) Provide an accurate description of the bug with detailed steps for
+ how we can reproduce the problem.
+
+3) If possible provide a minimal test case demonstrating the bug. A
+ great test case would be a minimal self-contained function in C or
+ python or whatever language you are using for cairo. The function
+ might accept nothing more than a cairo context, (cairo_t* in C).
+
+4) If you feel like being particularly helpful, you could craft this
+ minimal test case in the form necessary for cairo's test
+ suite. This isn't much more work than writing a minimal
+ function. Just look at the cairo/test/README file and imitate the
+ style of existing test cases.
+
+ If you do submit a test case, be sure to include Copyright
+ information, (with the standard MIT licensing blurb if you want us
+ to include your test in the test case). Also, including a reference
+ image showing the expected result will be extremely useful.
+
+5) Finally, the best bug report also comes attached with a patch to
+ cairo to fix the bug. So send this too if you have it! Otherwise,
+ don't worry about it and we'll try to fix cairo when we can.
+
+Thanks, and have fun with cairo!
