+## Initializing Submodules
+
+Test suite `llm-enhanced-test` is maintained in separate repository and included as git submodule. You need to initialize it before building.
+
+```bash
+git submodule update --init --recursive
+```
+
+Alternatively, if you haven't cloned the repository yet, use `--recursive` when cloning:
+
+```bash
+git clone --recursive https://github.com/bytecodealliance/wasm-micro-runtime.git
