How can I contribute Add-on?
How can I use “Commercial Vaadin Add-on Licence v3” with this Add-on?
Any rules to follow?
Thanks,
This page contains good information on publishing add-ons:
https://vaadin.com/directory/help/creating-vaadin-add-ons#publishing-an-addon
And
https://vaadin.com/terms-of-service
lists rules and the possible licenses you can have (open-source). CVALv3 is not possible.
