VS Code - Connect to remote GIT repository and PUSH local files to new remote repository

I have created a local project with Visual Studio Code that implements a local GIT repository.

Then I have create a GIT repository on Visual Studio Online and I want to PUSH all my project files to the remote repository...

What is the correct procedure to do it ?

My .git\config files in this moment look like this:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    precomposeunicode = true

Thanks to support
