Development

To regenerate the proto files, ensure you have installed the generate dependencies:

$ make install
go install \
        ./vendor/github.com/gogo/protobuf/protoc-gen-gogo
go mod vendor      

It also requires you to have the Google Protobuf compiler protoc installed. Please follow instructions for your platform on the official protoc repo.

Regenerate the files by running make generate:

$ make generate
