Where i can to find a tutorial for Task?

The University of Quindio has adopted Nextcloud as its platform for private cloud and is very interested in the Task application for the management of projects of a working group of 30 people. I want to know if this app allows you to manage tasks of a group of that number of people for a common project and if there is a manual or tutorial that allows us to study to perform several tests on the Task app. Thank you very much for your attention and support.

You might be interested in the official support from Nextcloud GmbH, they have more experience in running large setups and probably have more information on specific apps and how they scale in these environments (they have a few educational customers).
