-> WSL 2 is not "version 2" of WSL, but more "layer 2" WSL 1 uses a Linux syscall
-> wrapper around the Windows Kernel WSL 2 uses `VirtualMachinePlatform` and
-> Hyper-V to run a full Linux kernel with 100% syscall compatibility.
-
-After installing WSL and **Rebooting** you will be able to install Linux
-variants from the Windows 10 Store:
-
-- [Ubuntu Linux 20.04](https://www.microsoft.com/store/apps/9n6svws3rx71)
-- [Alpine WSL](https://www.microsoft.com/store/apps/9p804crf0395)
+> The Windows Subsystem for Linux has two modes:
+>
+> - **_WSL 1_** - a Windows Kernel syscall wrapper (similar to WINE)
+> - **_WSL 2_** - a true Linux Kernel run with Hyper-V virtualization
+>
+> Each mode has its
+> [tradeoffs](https://docs.microsoft.com/en-us/windows/wsl/compare-versions),
+> but the main differences are that WSL 1 has better compatibility with
+> inexpensive laptops and better seemless integration with the Windows file
+> system and that WSL 2 can run certain low-level software (such as for
+> networking and virtual file systems) that WSL 1 cannot.
+
+Once installed,
+[Ubuntu Linux 20.04](https://www.microsoft.com/store/apps/9n6svws3rx71) will be
+available from the **Windows Start Menu**.
+
+You can use the `wsl` command to start Ubuntu Linux with the `wsl` command, but
+only **after** clicking on it in the Windows Start Menu to add a `username` and
+`password`.
+
+- **Username**: We recommend `app` as the username (this is a common convention)
+ - The `root` (admin) account always exists, no matter what username you pick
+- **Password**: You can change the password at any time:
+ - For `app`: `wsl -u root passwd app`
+ - For `root`: `wsl -u root passwd`
