 ### Running
 
-Get an `sample_wasi_http_rust.wasm` from [the sample
-repo](https://github.com/bytecodealliance/sample-wasi-http-rust), either
-by building it or by fetching it from the OCI registry:
+Build the guest component:
 ```sh
-wkg oci pull ghcr.io/bytecodealliance/sample-wasi-http-rust/sample-wasi-http-rust:latest -o sample_wasi_http_rust.wasm
+cargo component build --release \
+    --manifest-path guest/Cargo.toml \
+    --target-dir target
 ```
 
 AOT compile it:
 
 ```sh
-cargo install hyperlight-wasm-aot --git https://github.com/jprendes/hyperlight-wasm.git --rev 134d8fc35
-hyperlight-wasm-aot compile --component sample_wasi_http_rust.wasm sample_wasi_http_rust.bin
