On GitHub, topics are used in the Explore section of the site. Topics can be used by developers in your community to "tag" their repositories – and it's very likely if you have any ecosystem at all, people have added a topic for your product (they just get automatically created so whatever the most popular one is wins in the autocomplete).

Have a lovely day,
