+## Smoke test
+
+Use [classification-example](https://github.com/bytecodealliance/wasi-nn/tree/main/rust/examples/classification-example) as a smoke test case to make sure the wasi-nn support in WAMR is working properly.
+
+> [!Important]
+> It requires openvino.
+
+### Prepare the model and the wasm
+
+``` bash
+$ pwd
+/workspaces/wasm-micro-runtime/core/iwasm/libraries/wasi-nn/test
+
+$ docker build -t wasi-nn-example:v1.0 -f Dockerfile.wasi-nn-example .
+```
+
+There are model files(*mobilenet\**) and wasm files(*wasi-nn-example.wasm*) in the directory */workspaces/wasi-nn/rust/examples/classification-example/build* in the image of wasi-nn-example:v1.0.
+
+### build iwasm and test
+
+*TODO: May need alternative steps to build the iwasm and test in the container of wasi-nn-example:v1.0*
+
+``` bash
+$ pwd
+/workspaces/wasm-micro-runtime
+
+$ docker run --rm -it -v $(pwd):/workspaces/wasm-micro-runtime wasi-nn-example:v1.0 /bin/bash
+```
+
+> [!Caution]
+> The following steps are executed in the container of wasi-nn-example:v1.0.
+
+``` bash
+$ cd /workspaces/wasm-micro-runtime/product-mini/platforms/linux
+$ cmake -S . -B build -DWAMR_BUILD_WASI_NN=1 -DWAMR_BUILD_WASI_EPHEMERAL_NN=1
