  Installing Windows Subsystem for Linux
  ---------------------------------------
  -With Windows 10, Microsoft has released a new feature named the [Windows
  -Subsystem for Linux (WSL)](https://docs.microsoft.com/windows/wsl/about). This
  -feature allows you to run a bash shell directly on Windows in an Ubuntu-based
  -environment. Within this environment you can cross compile for Windows without
  -the need for a separate Linux VM or server. Note that while WSL can be installed with
  -other Linux variants, such as OpenSUSE, the following instructions have only been
  -tested with Ubuntu.
  -
  -This feature is not supported in versions of Windows prior to Windows 10 or on
  -Windows Server SKUs. In addition, it is available [only for 64-bit versions of
  -Windows](https://docs.microsoft.com/windows/wsl/install-win10).
  -
  -Full instructions to install WSL are available on the above link.
  -To install WSL on Windows 10 with Fall Creators Update installed (version >= 16215.0) do the following:
  -
  -1. Enable the Windows Subsystem for Linux feature
  - * Open the Windows Features dialog (`OptionalFeatures.exe`)
  - * Enable 'Windows Subsystem for Linux'
  - * Click 'OK' and restart if necessary
  -2. Install Ubuntu
  - * Open Microsoft Store and search for "Ubuntu 18.04" or use [this link](https://www.microsoft.com/store/productId/9N9TNGVNDL3Q)
  - * Click Install
  -3. Complete Installation
  - * Open a cmd prompt and type "Ubuntu1804"
  - * Create a new UNIX user account (this is a separate account from your Windows account)
  -
  -After the bash shell is active, you can follow the instructions below, starting
  -with the "Cross-compilation" section. Compiling the 64-bit version is
  -recommended, but it is possible to compile the 32-bit version.
  +Follow the upstream installation instructions, available [here](https://docs.microsoft.com/windows/wsl/install-win10).
