Can I use Wekan as a CMS?

Hi, I'm a teacher and currently use Trello as a CMS, not as a "to-do" management. It is very easy and fast to use to organize content and programming of my courses at school. I can add formatted text (with markdown), images, videos, links, attach documents and files to each card, I can do searches, I can share it with colleagues and invite them to collaborate... It is taking a lot of time and effort and I would like to have all the data under my control, and I was wondering if I could use Wekan to do the same.

Thanks.
