Feel like this belongs to the website, can be a separate file to download or inlined in .md file.

Hi @Thepathakarpit, as a quick heads up, I am not a Windows user and do not know a lot about the best practices.
I like the idea of simplifying Windows installs, but I am not sure if adding another script is the solution here since we already have a GNUmakefile for sth similar.
I know that one can install GNU make via chocolatey and I assume it works similar to the linux version? I don't know how the integration for batch files is there but to hide the complexity and yet another script in the tree, maybe it's possible to go GNUmakefile way?
