How do I render a video with subtitles?

This might be a dumb question, but I have a problem with that. So I made a video and added subtitles to it (in the subtitle track). When I render it, it everything looks as I wanted but one thing is not there: the subtitles. I tried to use different settings but I do not know how to make them appear in the video.
Can anyone help? I would be really grateful!
