As a further option, there is also git add -i which is not a great UX and it has its own weird DSL with oddities, but still a slightly "higher level" than git add -p for when people need or want something less fine-grained than git add -p from the command line without installing another git porcelain. git add -i lets you get the status of files in the working directory, add entire files, revert entire files, or patch individual files, all from a single UI "session". You can do all of the same stuff with appropriate pathspecs to the individual commands such as git add -p just/one/file-i-need.md, but git add -i is an option for those that want an "almost GUI" for that.
