How will to upload codes on github

I have a lot of confusion regarding git and github
My laptop configuration is not same as yours so it is asking for permissions which I am unaware of since I am a beginner in webd. So will it be okay if I directly upload my codes on github by using upload file option.

Also if I upload my code on github how will you get to know about it?

Send a screenshot when git asks for “permissions”.

You cannot use the upload file for each and every file that you create. That would not be practical.

Once code is uploaded, you can visit the github repo and see the last commit.
