+# SMG gRPC Client (Go)
+
+This module contains auto-generated Go gRPC code for Shepherd Model Gateway services (SGLang, vLLM, TRT-LLM).
+
+## Installation
+
+To use this module in your Go project:
+
+```bash
+go get github.com/lightseek/smg/crates/grpc_client/go
+```
+
+## Package Structure
+
+The generated code is divided into packages under the `generated` directory:
+
+-   `generated/common`: Common types (e.g., KV Events)
+-   `generated/sglang_encoder`: SGLang Encoder service
+-   `generated/sglang_scheduler`: SGLang Scheduler service
+-   `generated/trtllm`: TensorRT-LLM Service
+-   `generated/vllm`: vLLM Engine service
+
+## Generation
+
+To regenerate the code from `.proto` files:
+
+1.  Install prerequisites:
+    ```bash
+    go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
+    go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
+    ```
+2.  Run the generation script:
+    ```bash
+    bash generate.sh
+    ```
+
+The generated code is committed to **Git release tags** automatically by the CI pipeline for convenience.
+
+> [!IMPORTANT]
+> When consuming this module in external projects, you **must** specify a version tag (e.g., `@v1.0.0`). Consuming the `main` branch directly will result in missing generated files due to full-tree `.gitignore`.
+
+
+## Release
+
+Releases are created automatically when the version in the `VERSION` file is updated and merged into `main`. It will create a Git tag: `crates/grpc_client/go/v<VERSION>`.
