+cd $HOME
+git clone https://github.com/WasmEdge/WasmEdge.git
+cd WasmEdge
+```
+
+3. Compile wasmedge with enabling the `wasi_nn_ggml` related options, please use the following commands. To build the plugin, you don't need to enable AOT/LLVM related features, so set them to OFF.
+
+##### CUDA Enable
+
+```console
+# CUDA ENABLE:
+& "C:\Program files\CMake\bin\cmake.exe" -Bbuild -GNinja -DCMAKE_BUILD_TYPE=Release -DWASMEDGE_PLUGIN_WASI_NN_BACKEND=ggml -DWASMEDGE_PLUGIN_WASI_NN_GGML_LLAMA_CUBLAS=ON -DWASMEDGE_USE_LLVM=OFF .
+& "<the ninja-build folder>\ninja.exe" -C build
+```
+
+##### CUDA Disable
+
+```console
+# CUDA DISABLE:
+& "C:\Program files\CMake\bin\cmake.exe" -Bbuild -GNinja -DCMAKE_BUILD_TYPE=Release -DWASMEDGE_PLUGIN_WASI_NN_BACKEND=ggml -DWASMEDGE_USE_LLVM=OFF .
+& "<the ninja-build folder>\ninja.exe" -C build
+```
+
+#### Execute the WASI-NN plugin with the llama example
+
+1. Set the environment variables
+
+```console
+$env:PATH += ";$pwd\build\lib\api"
+$env:WASMEDGE_PLUGIN_PATH = "$pwd\build\plugins"
+```
+
+2. Download the wasm and run
+
+```console
+wget https://github.com/second-state/WasmEdge-WASINN-examples/raw/master/wasmedge-ggml/llama/wasmedge-ggml-llama.wasm
+wget https://huggingface.co/QuantFactory/Meta-Llama-3-8B-Instruct-GGUF/blob/main/Meta-Llama-3-8B-Instruct.Q5_K_M.gguf
+wasmedge --dir .:. --env llama3=true --env n_gpu_layers=100 --nn-preload default:GGML:AUTO:Meta-Llama-3-8B-Instruct.Q5_K_M.gguf wasmedge-ggml-llama.wasm default
