Details

This command will cause a package to be extracted in a temporary directory intended to be editable at will.

Once you're done with your changes, run yarn patch-commit -s <path> (with <path> being the temporary directory you received) to generate a patchfile and register it into your top-level manifest via the patch: protocol. Run yarn patch-commit -h for more details.
