HaskellerZ Meetup Group

Main HaskellerZ meetup page.

This repository mainly hosts the slides from past meetups. The README moreover serves as a drafting document for upcoming meetups.

In general, we'll have a HaskellerZ meetup every last thursday of January until October every year. Note that we welcome guests and will happily adjust our schedule if they would like to give a talk.
