You don't have to create folder inside public. Please follow the proper file order of this repository. filename should not v default(index,style,script) Css and js must be in assets folder. Change every linkage accordingly.

You don't have to make changes in README. It's not needed, I closed your issue related to this.

You must review it again it's not the change made by me in the readme, it's reflected in my PR because I merged it with the updated branch of yours, also being active in the world of open source I would like to suggest that the hierarchy that you are following in your project is not professional and globally accepted.

Hope this helps.

Thanks for the suggestion about file hierarchy, will revamp it after GSSoC.
