How to upload website to Netlify from src

Hello, I just finished frontend mentor challenge and I have problems with deploying a site on netlify. It's my first time using tailwind, npm scripts and tooling. I also had some problems with git branches, but I think it's good now. I don't really have the build command (I was thinking maybe the npm run start is the build command but it also wasn't working). The netlify is showing the "page is not exisiting". On the GitKraken it looks like on the screen. Also the .gitignore file isn't working properly, it ignores for example node_modules/ but not dist/
EDIT. I managed to upload a website from GithubPages, but I am still curious how to do it via Netlify github: https://github.com/Jakub-Gryczka/age-calculator github pages: https://jakub-gryczka.github.io/age-calculator/ netlify: https://leafy-beijinho-bb403d.netlify.app/
