I do not understand the problem. It's just a directory, there shouldn't be any problems with or without the trailing slash. Both URLs https://github.com/GitAlias/gitalias/tree/main/doc/git-topic/ and https://github.com/GitAlias/gitalias/tree/main/doc/git-topic show me the same directory.

You're right, I made some unnecessary changes, sorry. It's this link that doesn't work for me: [git topic-*](git-topic/) I changed it to [git topic-*](doc/git-topic/)
