Question about comercial use of KanjiVG for japanese lessons from a Chinese Press

[Luis Chou]

Hello,

Thank you for creating an incredible open-source project for Kanji stroke orders.

I write this question for asking the copyright problem of comercial use.

I'm editor of a Chinese press, and I'm preparing for a set of 10 video lessons linking to a book for beginners of Japanese. In the videos lessones, I would like to use Kanji stroke orders for the understading of readers.

So, as I'm little known to the CC BY-SA 3.0. terms, I would like to ask for if it is free to use (with no change) the orders in my ppt and how to write the proper sentence for the cita？

Thank you for your time and for your continued contributions to the community.
