I came to know a great article for installing and using SASS on Windows after struggling while on you tube and lynda.com. Its very great to start with internally https://medium.com/@ricardozea/sass-for-beginners-the-friendliest-guide-about-how-to-install-use-sass-on-windows-22ff4a32c1f7
Hoping to help follow campers with SASS. If you have anyting interesting regards to SASS/SCSS. Please do share.
