rg90 The asterisk is the version requirement - quotes are used so the command shell doesn't try to resolve a file from it (* usually refers to all files & directories).
* in version constraints will resolve for all versions that are compatible with your current. We use it for people who are in older versions that are not supported by the latest extension version - for example, before v1 was released, if an extension was updated for v1, you'd get an error when trying to install it. * solves that issue because it installs whatever version is the newest that is still compatible with your setup.
Hopefully that made sense - I may have overcomplicated some explanations.
