-Protocol Buffers and gRPC specifications for the Jelly protocol.
+Protocol Buffers and gRPC specifications for the Jelly RDF serialization format and gRPC streaming protocol.
 
 - `rdf.proto` – the RDF Protocol Buffers serialization only. Use this if you don't plan on using Jelly's gRPC protocol.
 - `grpc.proto` – Jelly's gRPC protocol service specifications.

 ## Usage
 
 The `rdf.proto` and `grpc.proto` files define the Jelly RDF serialization and the gRPC pub/sub service, respectively. They use the [proto 3](https://protobuf.dev/programming-guides/proto3/) language and can be used with protoc or any other compatible tool. See the [Protocol Buffers documentation](https://protobuf.dev/) for more details.
