+Contributing
+============
+
+Simple patches can be sent directly to the users mailing list. With more
+elaborate contributions, please create your own fork and send just a link
+to your public repository, including the appropriate branch name(s)
+and Git commit hash(es)
+
+Please note that we are keeping mergability of the stable version 2 with
+the multithreaded version 3. Every contribution must be mergable to both
+branches master and thread-next. In case of collisions, the contributor
+shall provide two branches / patches, one mergable to master, another
+to thread-next.
+
+Alternatively, the contributor may omit the version 2 implementation and
+contribute to version 3 only. We are planning to declare the version 3
+stable as soon as possible. Don't worry, your contribution won't be lost.
+
+If you need any help of guidance, feel free to ask. The maintainers are
+quite busy though (as of Jan 2024). You are expected to ping the maintainers
+relentlessly until they react and review your contributions.
