How to send brunch to server?

Question

git

We’ve been sorting it out for the third day and don’t understand how to send changes at all?
I tried a million and one instructions, but all the time the same thing: it asks for a login, password, after which it says that there is no access, the URL returns 403. The author has already made a branch manually, I can’t go there either. I made a fork, I can't go there either. Always absolutely the same.

Answer 1

Maybe two-factor authentication? Or try pulling the project first so that you have the changes on the server (although 403 is not about that, but still).

Answer 2

git clone ....
echo "Hello" > a.txt
git add a.txt
git commit -m "Add a.txt"
git push origin master

Which server do you want to push changes to? Github?
