Website is not showing on GitHub Pages after deployment - reactjs

Question

This is my first time deploying onto GH Pages and it seemed like everything was right. It states "Your site is published at https://shayanvalaie.github.io/portfolio/" but after going to the address it gives me a getting started with react page.
After doing some research I found that it might be due to the fact that it is taking my master branch and the solution was to change to the gh-pages branch but after checking it seems I don't have a gh-pages branch.
This is my package.json
"homepage": "https://shayanvalaie.github.io/portfolio/",
"name": "portfolio",
"version": "0.1.0",
"private": true,
"dependencies": {

},

},

},

I found the solution. I was following a botched tutorial and it missed the step where I need to run "npm run deploy".
