I will send more details to those that sign up but we are planning a kick off meeting with an introduction to the library and then asking participants to sign up to implement issues and by the end of the hackathon be able to release the library as version 1.0. The hackathon will be held during the following times:
3:00pm - 7:00pm CEST
2:00pm - 6:00pm BST
9:00am - 1:00pm EDT
Thanks
