MathComp Sharing Days 🥳

The MathComp sharing days are an opportunity to share your experience using MathComp with newcomers, if you have questions about using the MathComp library, or for discussions about more advanced projects using MathComp are also welcome. The meetings happen every last Wednesday of the month (Paris timezone).

See https://github.com/math-comp/math-comp/wiki/TopicsNextMeeting on how to join.

The registration is not mandatory, but it would help us have more visibility on the event.
