+> ## Service Naming (Multi-Proto File Support)
+>
+> By default, the service name is derived from the **proto package name** (e.g., `package user;` → service name `user`).
+> This enables splitting a large proto file into multiple smaller files that share the same package name,
+> which is particularly useful for AI-assisted development where smaller files are easier to process.
+>
+> **Example: Multiple proto files with same package**
+> ```
+> protos/
+> ├── user_base.proto      # package user;
+> ├── user_auth.proto      # package user;
+> └── user_profile.proto   # package user;
+> ```
+> All three files will generate into a single `user` service.
+>
+> **Legacy behavior (--name-from-filename)**
+>
+> If you need the old behavior where service name is derived from the proto filename,
+> use the `--name-from-filename` flag:
+> ```bash
+> goctl rpc protoc user.proto --go_out=./pb --go-grpc_out=./pb --zrpc_out=. --name-from-filename
+> ```
