Can one add tags to repositories and filter by these tags when searching for them?

Hello everyone,

in our agency, we work with a lot of different repositories.

Often, when explaining a task to a new developer, I will tell them to look in the repository xy, because I have done something similar there.

Is there a way to “tag” repositories in gitlab with certain keywords, so that others can filter our repositories to only show the ones with a certain filter?

Greetings
Daniel
