Bon jour JF, I see that you have already done what I am currently working on! I am writing a hackathon/ event handbook for the WMF. If you want, I will happily keep you in the loop and appreciate your feedback. :)

Dear JF, I'm allowing myself to publish a little info box at the top of your page, to inform everyone about our newly improved hackathon documentation. Please remove if that's not cool. Merci!
