This report serves as an accompanying document to Aurora RI deliverable 6.4 - Open Science Community starter kit and a platform for these communities to interact. This deliverable is the result of work carried out within the Aurora partner universities as part of the Horizon 2020 funded Aurora RI project. We supported the International Network of Open Science Communities (INOSC) to develop an incubator programme for starting Open Science communities. Using this programme, we created Open Science communities at 6 of our 9 Aurora partner universities. In these Open Science communities, students and researchers who want to learn about Open Science can share experiences and inspire each other. We are piloting a platform for connecting these local communities with each other.
