 ## Prerequisites
 
-To complete this lesson, you will need a Unix-like shell environment -see [Setup](learners/setup.md). You will also need to download the file **[shell-lesson.zip](https://raw.githubusercontent.com/librarycarpentry/lc-shell/gh-pages/data/shell-lesson.zip)** from GitHub to your *desktop* and extract it there (once you have unzipped/extracted the file, you should end up with a folder called "shell-lesson").

   - Double click the `.exe` file to run the installer (for example, `Git-2.42.0.2-64-bit.exe`) using the default settings.
   - Once installed, open the shell by selecting Git Bash from the start menu (in the Git folder).
 
-There are also some more advanced solutions available for running Bash commands on Windows. A Bash shell command-line tool is available for Windows 10, which you can use if you enable the [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10). You can also run Bash commands on a remote computer or server that already has a Unix Shell from your Windows machine. This can be done through a Secure Shell (SSH) client. One client available for free for Windows is [PuTTY](https://www.putty.org/).
