+## Windows (WSL2)
+
+NVIDIA NeMo Agent Toolkit is developed and tested on Linux and macOS. On Windows, the recommended path is to run the toolkit inside the Windows Subsystem for Linux 2 (WSL2). The steps in this section were verified on Windows 11 with Ubuntu 24.04 LTS. A GPU is not required, because the toolkit can call NVIDIA-hosted NIM endpoints.
+
+Complete the Windows-specific steps below, then continue with the standard [Install From Source](#install-from-source) steps, running every command inside the WSL2 Ubuntu shell.
+
+### Install WSL2 and Ubuntu
+
+From an Administrator `PowerShell` session, install WSL2 with an Ubuntu distribution, then restart the machine when prompted:
+
+```bash
+wsl --install -d Ubuntu-24.04
+```
+
+:::{note}
+To check whether WSL2 is already installed, run `wsl --status`. If the output reports a default distribution and `Default Version: 2`, WSL2 is ready and you can skip to the next step.
+:::
+
+### Set up the Linux user
+
+The first time Ubuntu launches, it prompts you to create a Linux username and password. This password is separate from the Windows password and is used for `sudo` commands inside Ubuntu.
+
+:::{note}
+To set or change the password later, run the following from an Administrator `PowerShell` session, replacing `<username>` with your Linux username:
+
+```bash
+wsl -u root
+passwd <username>
+exit
+```
+:::
+
+### Install build prerequisites
+
+Open Ubuntu (from the Start menu, or by running `wsl` in `PowerShell`) and install the build tools. Git Large File Storage (LFS) is required by the repository and is not included in the default Ubuntu image:
+
+```bash
+sudo apt update && sudo apt install -y curl git build-essential git-lfs
+```
+
+### Install uv
+
+Install [`uv`](https://docs.astral.sh/uv/) into your user directory:
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+:::{note}
+After installing, run `source $HOME/.local/bin/env` in the current shell, or close and reopen Ubuntu, so that the `uv` command is on your `PATH`.
+:::
+
+### Continue with Install From Source
+
+Follow the [Install From Source](#install-from-source) steps below. Run every command inside the WSL2 Ubuntu shell, not in `PowerShell` or `cmd`. After activating the virtual environment, the shell prompt begins with `(.venv)`; activate the environment in every new Ubuntu session before running `nat` or `uv` commands.

 ## Install from Package
 
 The package installation is recommended for production use.
