 *The academic year is about to start, 
 so why not learn ROOT with us?*
 
-During the summer, the ROOT team has organized a number of ROOT Summer Student courses at CERN and two HSF/IRIS-HEP Python for Analysis Trainings online, meaning the ROOT community has expanded by around 200 new students! And that is only the beginning; we think more students should have an opportunity to acquire the course material, this time in a self-study manner.
