Add the files in your new local repository. This stages them for the first commit.
Commit the files that you’ve staged in your local repository.

Navigate to where you want to store the repository:

cp the url and run:

Do some code changes, here we added a new file:

Then run the below code and the repository is updated

git add .
git commit -m "from new pc"
git push origin master

Change repository and work more there:

cd t-sql
git add .
git commit -m "change dir"
git push origin master

Branch, if the branch “test” was created and we did some some changes

git branch

git add .
git commit - m "my commit"
git push origin HEAD:test

git merge --no-f test
git push origin master
or
git push origin test
