Once enabled, a new Tasks menu will appear in your Nextcloud apps menu. From
there you can add and delete tasks, edit their title, description, start and
due dates, reminder times, mark them as important, and add comments on them.
Tasks can be shared between users. Tasks can be synchronized using CalDav (each
task list is linked to an Nextcloud calendar, to sync it to your local client -
Thunderbird, Evolution, KDE Kontact, iCal... - just add the calendar as a
remote calendar in you client). You can download your tasks as ICS files using
the download button for each calendar.
