How to: render static multilingual site

[Dmitry-N-Medvedev]

good morning, nice community :)

I have a seemingly very basic problem I have no idea how to address.

the context: there should be a simple site ( with a couple of server-side functions ) made up of a bunch of pre-rendered pages.

the problem: each page should be in 3 languages. each page should be static ( e.g. no database queries ). And I don't know how to do routing to a proper page provided that the viewer's language is specified in a store.

please direct me to documentation or give me at least some hints. I am very new to web development and kind of confused right now.

best regards,
Dmitry
