when I upload my redux project to GitHub, the project url opens its readme. On local PC I write npm start and everything works, the project is displayed, but on git hub, open only readme

I install gh-pages to my package.json, and add homepage with needed url “https://dimadamage91.github.io/Quizzes/”.
But this url open readme.
