 ## Building Pinecil V2
+
+To build the Pinecil V2 firmware, you can use a Docker container that provides a consistent development environment across different operating systems, including Windows with WSL2. Here's how to do it:
+
+### Prerequisites
+
+Docker Desktop: Install the latest version of Docker Desktop for your operating system from the official website.
+
+On Windows follow the instructions on the official documentation to install 'Windows Subsystem for Linux' (WSL2).
+
+### Building Steps
+
+1. Clone the repository, initialize and update submodules:
+
+    ```sh
+    git clone --recurse-submodules https://github.com/Ralim/IronOS.git
+    ```
+
+2. Start the Docker container with the development environment:
+
+    ```sh
+    cd IronOS
+    ./start_dev.sh
+    ```
+
+    This script will build a Docker image and run a container with the necessary tools to build the firmware.
+
+3. Build the firmware for Pinecil V2:
+
+    ```sh
+    cd source/source
+    ./build.sh -l EN -m Pinecilv2
+    ```
+
+    This command will compile the firmware with English language support for Pinecil V2 board.
+
+4. Find the firmware artifacts:
+    After the build completes successfully, you can find the firmware artifacts in the `source/Hexfile` directory.
