How to select language of the website depending on user's language?

Question

I am curious if anyone has done this before. I want to have two languages on my q2a website. The primary language of my site is Russian, but I am seeking for an option to automatically translate text to English if the visitor's user-agent indicates English.

To be more clear, here is a simple example:

1. User's user-agent shows Russian - the website will be on Russian
2. If the user's user-agent shows English - the website will be on English

Any ideas on how to implement this? Additionally, did anyone connect the q2a website to Google Translate to get an instant translation?

Comments

AFAIK this has been asked before but so far no one has done this. This should be possible via a plugin though it is not so straight forward.

Do you mean translating the interface (menu links, buttons, etc)? Or translating the content of everyone’s questions/answers?

Ideally, I'd like to translate everything.
