 ## Limitations
 
-- Flash is currently only available for macOS and Linux. Windows support is in development.
+- Flash runs natively on macOS and Linux. Windows users can run Flash through [WSL2](/flash/windows-wsl2).
 - CPU endpoints are restricted to the `EU-RO-1` datacenter. GPU endpoints can deploy to [multiple datacenters](/flash/configuration/parameters#datacenter).
 - Flash can rapidly scale workers across multiple endpoints, and you may hit your maximum worker threshold quickly. Contact [Runpod support](https://www.runpod.io/contact) to increase your account's capacity if needed.

+description: "Set up WSL2 with Ubuntu to run Flash on Windows."
+---
+
+Flash runs natively on macOS and Linux. On Windows, you can run Flash through Windows Subsystem for Linux (WSL2), which provides a full Linux environment on your machine.
+
+## Requirements
+
+- Windows 10 version 2004 or later, or Windows 11.
+- Administrator access to your Windows machine.
+- [Runpod account](/get-started/manage-accounts) with a verified email address.
+- [An API key](/get-started/api-keys) with **All** access permissions.
+
+## Step 1: Enable WSL2
+
+Open PowerShell or Command Prompt as Administrator (right-click and select "Run as administrator"), then run:
+
+```powershell
+wsl --install
+```
+
+This command enables WSL, installs the latest Linux kernel, sets WSL2 as the default version, and installs Ubuntu as your Linux distribution.
+
+<Tip>
+If WSL is already installed on your system, you can install Ubuntu specifically with:
+
+```powershell
+wsl --install -d Ubuntu
+```
+</Tip>
+
+After the installation completes, restart your computer when prompted.
+
+## Step 2: Set up Ubuntu
+
+After restarting, Ubuntu launches automatically and prompts you to create a Linux username and password. These credentials are separate from your Windows account and are used only within the Linux environment.
+
+If Ubuntu doesn't launch automatically, open it from the Start menu by searching for "Ubuntu".
+
+Once setup is complete, you'll see the Ubuntu terminal prompt:
+
+```text
+username@hostname:~$
+```
+
+Update your package lists to ensure you have access to the latest software:
+
+```bash
+sudo apt update && sudo apt upgrade -y
+```
+
+## Step 3: Install Python and uv
+
+Flash requires Python 3.10 or later. Ubuntu typically includes Python, but you should verify the version:
+
+```bash
+python3 --version
+```
+
+If you need a newer version, install it:
+
+```bash
+sudo apt install python3.12 python3.12-venv -y
+```
+
+Install [uv](https://docs.astral.sh/uv/), a fast Python package manager:
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+After installation, restart your terminal or run the following to add uv to your path:
+
+```bash
+source $HOME/.local/bin/env
+```
+
+## Step 4: Install and authenticate Flash
+
+Create a project directory and set up a virtual environment:
+
+```bash
+mkdir my-flash-project && cd my-flash-project
+uv venv
+source .venv/bin/activate
+```
+
+Install Flash:
+
+```bash
+uv pip install runpod-flash
+```
+
+Authenticate with your Runpod account:
+
+```bash
+flash login
+```
+
+This opens your browser to authorize Flash. After you approve, your credentials are saved.
+
+<Tip>
+Alternatively, you can set your API key directly:
+
+```bash
+export RUNPOD_API_KEY="your_key"
+```
+</Tip>
+
+## Step 5: Verify your installation
+
+Test that Flash is working correctly:
+
+```bash
+flash --version
+```
+
+You're now ready to use Flash. Continue with the [quickstart](/flash/quickstart) to run your first GPU workload.
+
+## Tips for working with WSL2
+
+**Accessing Windows files**: Your Windows drives are mounted under `/mnt/`. For example, `C:\Users\YourName\Documents` is accessible at `/mnt/c/Users/YourName/Documents`.
+
+**Opening WSL from any folder**: In Windows Explorer, type `wsl` in the address bar to open Ubuntu in that directory.
+
+**VS Code integration**: Install the [WSL extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-wsl) for VS Code to edit files in WSL with full IDE support. Run `code .` from your WSL terminal to open VS Code in the current directory.
+
+**Default terminal**: You can set Ubuntu as your default terminal in Windows Terminal for quicker access.
