+# CodeCtrl Protobuf Files
+
+This repository contains the files that define the communication between the
+CodeCtrl language loggers and the CodeCtrl log server that runs in the
+background. This repository is intended to be used as a submodule for each
+language logger to use to build against.
+
+gPRC-specific documentation for most languages can be seen
+[here](https://grpc.io/docs/languages/), though not all languages are listed.
+Rust has [tonic](https://crates.io/crates/tonic) which is what is being used
+inside CodeCtrl and works more than well enough. C has
+[juniper/gprc-c](https://github.com/juniper/grpc-c), but it seems unmaintained,
+may be worth using the main gPRC repo and using the core library instead as
+mentioned in the [table under this heading in the main
+repository](https://github.com/grpc/grpc#about-this-repository).
