How to support UPM in my Git repository?

UPM requires a package.json file at the root, or, alternatively for a UPM monorepo, one package.json file per subdirectory (typically with each of those directories inside /Packages). There are ways of doing this without changing your whole repository structure. Take a look at this amazing article by mob-sakai.

After you read that article, take a look at this tool for automating that process.
