[Feature Request]: Document about how to integrate with NvChad

### What?

Hi, I am trying to integrate bufferline.nvim with NvChad. But the result is NOT very good.

### Why?

By googling, there are not much information about it and no example demo config files. Since NvChad is one of most famous recommended config from neovim official website, hopefully, I can get a guide/document about how to do this integration.
