+## Usage
+
+### Via `rustapi-rs` (recommended)
+
+Add to your `Cargo.toml`:
+
+```toml
+[dependencies]
+rustapi-rs = { version = "0.1", features = ["grpc"] }
+```
+
+Then import via the `grpc` module:
 
 ```rust,ignore
 use rustapi_rs::grpc::{run_rustapi_and_grpc, tonic};
 use rustapi_rs::prelude::*;
 
 #[rustapi_rs::get("/health")]
 async fn health() -> &'static str { "ok" }
+```
+
+### Direct `rustapi-grpc` usage
+
+Add to your `Cargo.toml`:
+
+```toml
+[dependencies]
+rustapi-grpc = "0.1"
+rustapi-core = "0.1"
+```
+
+Then import directly:

+use rustapi_core::{get, RustApi};

+#[rustapi_core::get("/health")]
