To start using Indo with a monorepo, run the indo command.
This will find every nested .git repository. Then it asks which repositories should be automatically cloned for other developers when they run indo. Select "Add to vendor" to prevent other developers from using any of the packages inside the .git repository. Select "Add to repos" to let Indo clone it for other developers.
Now, commit the .indo.json file in your monorepo's root directory. This gives other developers the same configuration used by the indo command.
And you're done!
