+## WSL: Verification and Setup
+
+If you've chosen to use WSL, first verify that your installed version meets system requirements by running the following command in your terminal:
+
+```console
+wsl --version
+```
+
+If version details do not appear, you’re likely using the inbox version of WSL. This version does not support modern capabilities and must be updated.
+
+You can update or install WSL using one of the following methods:
+
+### Option 1: Install or update WSL via the terminal
+1. Open PowerShell or Windows Command Prompt in administrator mode.
+2. Run either the install or update command. For more information, refer to [Install WSL](https://learn.microsoft.com/en-us/windows/wsl/install).
+```console
+wsl --install
+
+wsl --update
+```
+
+### Option 2: Install WSL via the MSI package
+If Microsoft Store access is blocked due to security policies:
+1. Go to the official WSL GitHub Releases page: https://github.com/microsoft/WSL/releases
+2. Download the `.msi` installer from the latest stable release (under the Assets dropdown).
+3. Run the downloaded installer and follow the setup instructions.
