 #### How to get started
 
-Download the openRTB official 2.6 Protocol Buffers specification from https://github.com/InteractiveAdvertisingBureau/openrtb2.x/blob/main/proto/src/main/com/iabtechlab/openrtb/v2/openrtb.proto to this directory.
+`make generate` will fetch the OpenRTB 2.6 proto automatically. If you want to refresh it manually, run `make fetch-openrtb`.
 
 From the command line:
 
 1. Install `make` and the latest version of `protoc`.
-2. Open the `Makefile` and choose the language(s) for which the Protocol Buffers
-   object code should be generated.
-3. Run `make`.
+2. Choose the language(s) for which the Protocol Buffers object code should be generated.
+3. Run `make generate` or `make generate LANG=java`.
+
+#### Package names in generated code
+
+If you want generated code to use your own repo/package name, set the package options in the `.proto` files before generating code.
+
+Examples:
+
+- Go: `option go_package = "github.com/your-org/your-repo/pkg/pb/artf;artf";`
+- Java: `option java_package = "com.yourorg.yourrepo.artf";`
+- C++: `option cpp_namespace = "your::org::yourrepo::artf";`
+- Rust: use the generator/tooling-specific crate/module naming options for your Rust codegen pipeline
+
+#### Language selection with `make generate`
+
+You can pick one or more languages by passing a variable to `make`:
+
+```bash
+make generate
+make generate LANG=java
+make generate LANG=go,cpp,java
+make generate LANGS=rust
+```
+
+`LANG` and `LANGS` are both accepted; if neither is set, Go is generated by default.

+# Rust Example Service
+
+This directory contains the Rust reference implementation example for the Agentic RTB Framework (ARTF).
+
+It is a working example of a Rust gRPC service that follows the same contract as the Go implementation:
+
+```proto
+service RTBExtensionPoint {
+  rpc GetMutations (RTBRequest) returns (RTBResponse);
+}
+```
+
+## What this example does
+
+The example service:
+
+- generates Rust bindings from the proto definitions at build time
+- exposes a gRPC `RTBExtensionPoint` server
+- evaluates inbound requests and returns `RTBResponse` values
+- demonstrates how a Rust service can integrate with the ARTF mutation model
+
+## Build
+
+From the repo root:
+
+```bash
+cargo build --manifest-path Cargo.toml
+```
+
+## Run
+
+```bash
+cargo run --manifest-path Cargo.toml
+```
+
+The example starts its gRPC server and an HTTP server on the configured ports.
+
+## Proto source
+
+This example uses proto files under `examples/rust/proto/`:
+
+- `agenticrtbframework.proto`
+- `agenticrtbframeworkservices.proto`
+
+Those protos are written in `proto3` syntax and import the OpenRTB definitions:
+
+```proto
+import "com/iabtechlab/openrtb/v2.6/openrtb.proto";
+```
+
+The request and response messages include fields such as:
+
+- `RTBRequest`
+- `RTBResponse`
+- `Mutation`
+- `Metadata`
+- `BidRequest` / `BidResponse` from OpenRTB
+
+## Important caveat
+
+This example is intentionally using a proto3-based compatibility layer that references the OpenRTB schema, rather than directly compiling the repo’s newest canonical proto declarations.
+
+The repo’s top-level proto definitions use newer proto syntax (`edition = "2023"`). The Rust toolchain in this environment does not fully parse that syntax through the installed `prost`/`tonic` stack, so the example project uses the compatible `proto3` arrangement under `examples/rust/proto/`.
+
+This keeps the Rust example buildable while preserving the same ARTF service contract and OpenRTB shape.
