How to contribute to MonetDB

Hello! I find MonetDB as a software product interesting and would be interested in contributing to its development (and learning about In-Memory databases in the process) . The documentation for setting up the development environment and for getting the source code is pretty good, but I am missing a process description, how a volunteer can participate in the software development process. E.g. how are bugs assigned, how are patches submitted, what needs to be done besides code production? Is there a description of sorts? Best regards Jörg -- Jörg Strebel Aachener Straße 2 80804 München
