After Exporting the code of my project, how do I integrate my CMS to the existing project?

I was exporting the project codebase I was working, to my local computer. I wanted to now import my CMS which I was created in the project. But it is not easy to do.

When Um running the export codebase from Visual studio using the live server. But I can see the site is not working since CMS is not there.

Can someone help me to sort this issue?
