Howto for multilanguage sites?

[7iomka]

Hi, thanks for awesome workflow example!
Buy I have one big problem.
My site is multilanguage.
In django templates I use {% trans 'some text' %} or {% blocktrans %}some text{% endblocktrans %}
This strings is collected somehow with django (I don't know how, because I only newbie at this project and I only frontender)
So, need to allow django to search through all vue files.
But my knowledge in Django is not enough.
What I was looking for and what might be useful:
