I won't display some info here as what GitHub suggested. You are already in my profile page right? So why don't you just read my info from sidebar?
Also if I want to present myself, I have website hosted via GitHub Pages, which contains CSS, so I can customize it.
Again, GitHub, or Micro$oft, this is not a useful feature, users cannot write CSS in Markdown files. My website is better than your README in profile, completely.
