+Gitaly is part of GitLab. It is a server application that uses its own gRPC
+protocol to communicate with its clients. This repository contains the protocol
+definition and automatically generated wrapper code for Go and Ruby.
+
+The .proto files define the remote procedure calls for interacting with Gitaly.
+We keep auto-generated client libraries for Ruby and Go in their respective
+subdirectories.
+
+Use the make generate script from the root of the repository to regenerate the
+client libraries after updating .proto files.
