does the langases plug in work with WP single site?

hi there i wanted to ask you if the languages plug in works with wp single site. I installed the pack as instructed in your site and i could not see the languages drop down option in my setting tab. i am using wp v3.51.

It seems to me the lang pack only works in multi sites but you state that it works with the single installs. I want to make sure!

thank you.
