Unable to integrate downloaded HTML template in wordpress Theme

Question

I am trying to Convert my HTML template into Wordpress template.But on browser it is only showing content without CSS. I refered the procedure from: https://www.elegantthemes.com/blog/tips-tricks/converting-html-sites-to-wordpress-sites here I added a below given statement on the top of a CSS file.I am confused about what to write in Theme URI and Author URI, as Right now I am workin on localhost server.

/*
Theme Name: ThemeIntegration
Theme URI: ??
Description: A brief description.
Version: 1.0
Author: You
Author URI: ??
*/

I am only getting Simple html content without styling.

You need to add css and js files either in header or functions.php file, that tutorial is incomplete you can refer this link

If you have only 1 css then you can directly write it in style.css
