Need some help in Github

Hello,

Is there any feature like this,

Example - A developer has created a website and uploaded it to a website. I download and edit the website file and I create a git repo and pushed it. The developer added some features to the website and uploaded them to the website( we can call it an update). I download the update file and edit the same thing before I have done it. Now how can I push this in the same repo?

Regards,
Abhijeet

just using GitHub and GitHub Pages, you can host the site directly on GitHub, even without downloading the file to be updated,

any past changes can be restored using Git or GitHub Desktop, I think that’s your last question
