How does ".vtt" file work?

Hello guys, I was reading a bit about videos and audios on MDN and came across ".vtt" file extensions. I'm a bit confused about that, how does it work? Do we take, say an audio then change its file extension to .vtt?

I know it's used for subtitle/translations etc but don't really know how is it used

It's a specific file format for subtitles Changing an audio filename to .vtt will do nothing, it won't magically produce subtitles You just have to make one

oh ok, like for every timestamp I should write the subtitles?

Basically, though I assume there's software to help with that
