You can refer to usage guidelines on dockerhub https://hub.docker.com/r/bhupeshimself/ugit

Yes, that was also an internal motivation behind doing this.

Hey fzf is required by ugit (the script) itself. I didnt want to rely on cli arguments to give ability to users undo command per a matching git command. Adding a fuzzy search utility makes it easier for people to search what they can undo about "git tag" for example.
