 ### Build Bindings
 
-TODO: Add instructions
+#### Build OpenVINO GenAI as OpenVINO Extra Module
+
+OpenVINO GenAI Node.js bindings can be built as an extra module during the OpenVINO build process. This method simplifies the build process by integrating OpenVINO GenAI directly into the OpenVINO build.
+
+1. Clone OpenVINO repository:
+   ```sh
+   git clone --recursive https://github.com/openvinotoolkit/openvino.git
+   ```
+1. Configure CMake with OpenVINO extra modules:
+   ```sh
+   cmake -DOPENVINO_EXTRA_MODULES=*relative (from openvino folder) path to genai repository* -DCPACK_ARCHIVE_COMPONENT_INSTALL=OFF \
+         -DCPACK_GENERATOR=NPM -DENABLE_JS=ON -UTBB* -DENABLE_SYSTEM_TBB=OFF \
+         -DENABLE_PYTHON=OFF \
+         -DENABLE_WHEEL=OFF \
+         -DCPACK_PACKAGE_FILE_NAME=genai_nodejs_bindings \
+         -S ./openvino -B ./build
+   ```
+1. Build OpenVINO archive with GenAI:
+   ```sh
+   cmake --build ./build --target package -j
+   ```
+
+1. In `build` folder you will find `genai_nodejs_bindings.tar.gz`.
+   Create `bin` directory by path `src/js/` and unarchive archive content to it.
+1. Run tests to be sure that everything works:
+   `npm test`
 
 ### Perform Test Run
 
 - To run sample you should have prepared model.
-  Use this instruction [to download model](https://github.com/openvinotoolkit/openvino.genai/blob/master/samples/cpp/chat_sample/README.md#download-and-convert-the-model-and-tokenizers)
-- Go to [samples/js](../../samples/js/)
-- Run `node app.js`, you should see: `User Prompt: ...`
+  Use this instruction [to download model](https://github.com/openvinotoolkit/openvino.genai/blob/master/samples/js/chat_sample/README.md#download-and-convert-the-model-and-tokenizers)
+- Go to [samples/js/chat_sample/](../../samples/js/chat_sample/)
+- Read [README.md](../../samples/js/chat_sample/README.md) and follow steps there
+  to run **chat sample**.
