Being new to jekyll ( coming from python ), I am finding it tough to implement carousel on a page. Please suggest what steps i must take to have a fully functional carousel from the link below.

carousel slider with jekyll

link to my page: https://singhaidotnish.github.io/agency-jekyll-theme/

link to repository: https://www.github.com/singhaidotnish/agency-jekyll-theme/

I tried this carousel slider with jekyll above which gives a step by step instruction. Not sure what is missing but sure that something is missing on my part, called a blind spot.

If you know how this works, please suggest a way out of this.

Thank you
