Newbie to siyuan. Is there a tutorial for newbies?

Hi there,

I'm a python developer and a newbie to siyuan.

I am bilingual in chinese and english, but not a Chinese national.

I found most of the english tutorial, etc to be somewhat lackluster.

I am most impressed by the transclusion feature in Siyuan.

Is there a good tutorial (written, video, etc) for newbies? I am ok even if it's in Mandarin.

Thank you.
