+# Build Documentation with Development Container
+
+This guide shows how to use WSL2 (Windows Subsystem for Linux), Docker Desktop, Visual Studio Code (VS Code), and how to work with Development Containers in VS Code on a Windows machine.
+
+Requirements:
+ - [VS Code](https://code.visualstudio.com/)
+ - [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install)
+ - [Docker Desktop](https://docs.docker.com/desktop/setup/install/windows-install/)
+
+## Verify installations & Setup
+
+You can verify the installations in a terminal:
+
+   ```bash
+   code --version
+   wsl --version
+   docker --version
+   ```
+
+### Configure Docker to Use WSL2
+
+   See [Docker Desktop Documentation](https://docs.docker.com/desktop/features/wsl/#turn-on-docker-desktop-wsl-2).
+   - Open Docker Desktop.
+   - Go to **Settings > General** and make sure **Use the WSL 2 based engine** is checked.
+   - Under **Settings > Resources > WSL Integration**, ensure that your desired Linux distribution(s) are selected for integration with Docker.
+
+### Install Extensions
+
+   - Open Visual Studio Code.
+   - Press `Ctrl+Shift+X` to open the Extensions view.
+   - Search and install (includes WSL and Dev Containers Extensions):
+      - [Remote Development Extension Pack](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.vscode-remote-extensionpack)
+
+   VS Code Documentations:
+   - [Developing in WSL](https://code.visualstudio.com/docs/remote/wsl)
+   - [Developing inside a Container](https://code.visualstudio.com/docs/devcontainers/containers)
+
+
+## Build & Open the Development Container
+
+   - Open the project `doubleml-docs` in VS code:
+
+   ```bash
+   code .
+   ```
+
+   - Open the Command Palette (`Ctrl+Shift+P`).
+   - Type `Remote-Containers: Reopen Folder in Container`.
+   - VS Code will build the new container(this may take some time) and open the project in it.
+
+
+## Build the documentation
+
+You can build the documentation via
+
+   ```bash
+   cd doc
+   make html
+   ```
+
+   Open the directory in WSL with
+   ```bash
+   explorer.exe .
+   ```
