The library mentioned in the Readme (google/protobuf) does not exist in packagist and can't be pulled by composer.
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package google/protobuf could not be found in any version, there may be a typo in the package name.
It hasn't been pushed yet because it's not in any of the releases. Should come soon.
Awesome. Thanks!
