+Build ACRN Configurator From Source Code
+*****************************************
+
+The :ref:`prerequisites<acrn_configurator_tool_prerequisites>` use a prebuilt
+Debian package to install the ACRN Configurator. The following steps describe
+how to build the Debian package from source code. 
+
+#. On the development computer, complete the steps in :ref:`gsg-dev-computer`.
+
+#. Install the ACRN Configurator build tools:
+
+   .. code-block:: bash
+
+      sudo apt install -y libwebkit2gtk-4.0-dev \
+         build-essential \
+         curl \
+         wget \
+         libssl-dev \
+         libgtk-3-dev \
+         libappindicator3-dev \
+         librsvg2-dev \
+         python3-venv
+
+#. Install Node.js (npm included) as follows:
+
+   a. We recommend using nvm to manage your Node.js runtime. It allows you to
+      switch versions and update Node.js easily.
+
+      .. code-block:: bash
+
+         curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash
+
+   #. Rerun your ``.bashrc`` initialization script and then install the latest
+      version of Node.js and npm:
+
+      .. code-block:: bash
+
+         source ~/.bashrc
+         nvm install node --latest-npm
+         nvm use node
+
+#. Install and upgrade Yarn:
+
+   .. code-block:: bash
+
+      npm install --global yarn
+
+#. Install rustup, the official installer for Rust:
+
+   .. code-block:: bash
+
+      curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+   When prompted by the Rust installation script, type ``1`` and press
+   :kbd:`Enter`.
+
+   .. code-block:: console
+
+      1) Proceed with installation (default)
+      2) Customize installation
+      3) Cancel installation
+      >1
+
+#. Configure the current shell:
+
+   .. code-block:: bash
+
+      source $HOME/.cargo/env
+
+#. Install additional ACRN Configurator dependencies:
+
+   .. code-block:: bash
+
+      cd ~/acrn-work/acrn-hypervisor/misc/config_tools/configurator
+      python3 -m pip install -r requirements.txt
+      yarn
+
+#. Build the ACRN Configurator Debian package:
+
+   .. code-block:: bash
+
+      cd ~/acrn-work/acrn-hypervisor
+      make configurator
+
+#. Install the ACRN Configurator:
+
+   .. code-block:: bash
+
+      sudo apt install -y ~/acrn-work/acrn-hypervisor/build/acrn-configurator_*_amd64.deb
+
+#. Launch the ACRN Configurator:
+
+   .. code-block:: bash
+
+      acrn-configurator
