 ## What does `ocwd` do?
 `ocwd` is a command line utility that downloads resources from any [MIT OCW](https://ocw.mit.edu/) course to any storage path provided by you. The resources are available under the creative commons license and MIT reserves all rights to the content. This tool simply scrapes the OCW website for resources and offers a simple and easy way for downloading any course resource for offline use.
 ## Installation Guide
-> This script only works on 🪟Windows.
+> This script only works on 🪟Windows (🐧Linux + 🍎MacOS support coming soon!)
 
-`ocwd` requires Microsoft's cross-platform [PowerShell-Core](https://github.com/PowerShell/PowerShell/), if you don't have it already installed, read their [installation guide](https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.3).
+`ocwd` works with both Windows PowerShell and the cross-platform PowerShell-Core. 
 
-This tool works best with PowerShell-Core `v7.x.x`. That means, it is recommended to update your PS installation to the latest available version. 
+All recent versions of Windows 10 & 11 already come with Windows PowerShell installed (search for `PowerShell` using Windows Search to find out whether you have it or not). However, you can also follow the installation guides provided here in case you don't have PowerShell installed. 
 
-If you are installing a script for the first time, the following instructions will help you get started, otherwise you can skip ahead to the installation script. 
+If you have PowerShell installed, skip to the `ocwd` installation script.
 
-With the latest version available, we need to set the `ExecutionPolicy` to `RemoteSigned` as the default one is unsuitable for running user downloaded script. 
-Next, we need to set [PSGallery](https://www.powershellgallery.com/packages/ocwd) as a trusted source for our scripts, as `ocwd` is hosted at PSGallery repository.
