Emmanuel Katto Uganda | How to add tags in PeerTube?

Hello, my name is Emmanuel Katto and I am from Uganda. I just added a video in PeerTube but didn’t find any option of adding a tag, can anyone help me in finding the option where I can add the tags in PeerTube?

In the Peertube’s Documentation, it is write that

While the video is uploading you can set some details.

If you follow the link « some details », you can see that in the basic info category, the second bullet point is about the tag. So I think that it’s at this moment that you can add tags.
I don’t know if it helps you a lot, and sorry for my bad english.

Bests regards
