Updated agenda for hackathon, including timing of Zoom meetings

Bo Weidema

Hi all,

I have updated the agenda ( https://github.com/BONSAMURAIS/hackathon-2019/blob/master/Agenda.md ) with timing, including the timing of zoom meetings (all in BCN time).

Some one will probably have to revise the content, depending on the progress in the different preparation groups.

Best regards
