How to create a new branch and work with it?

Question

git

Such a question:
I create a new branch: git checkout -b remastered (thus I switched to it) I

add files: git add .

Commic: git commit -m "New files"

I get this:
On branch remastered
nothing to commit, working tree clean

In addition, please tell me how to create a new branch, add files to it and upload to the repository.
I will be very grateful in advance.

Answer 1

git checkout -b remastered
So they create a new branch and immediately go to it
git add .
that's right, you add changed files to tracking git commit -m "
New files "

Answer 2

Check for indexed files via
git status
Your error says that there are no files in the commit
