Github page showing README data

I’m using github to host my web page ,but I’m confused why it is showing README.md data in place of my webpage while using the url.

Link to my Repository
Link to my GitHub page

Have you followed the steps here including creating the index.html?

It become more messy senior even though I have already deleted read-me it stay show read-me only and I have search myself on internet for many hours but It doesn’t work can you please review my repository I am building portfolio with next.js

I’m not entirely sure what your question is right now.
This is the link to your website. It works for me:
https://saylyean.github.io/

The content may not be what you wanted it to be though.
But the actual website is up.
To change the content you must create a valid index.html

I hope you know how to do that?

The readme is supposed to display for a repository.
