You cannot push anything that hasn't been committed yet. The order of operations is:
- Make your change.
- git add - this stages the changes in the file for committing
- git commit - this will commit your staged file locally and now being tracked by git.
- git push - this will push your committed changes in a file to a remote repo
If you push without committing, nothing gets pushed. If you commit without adding, nothing gets committed. If you add without committing, nothing at all happens, git merely remembers that the changes you added should be considered for the following commit.
The message you are seeing (your branch is ahead by one commit) means your native repository has one commit that hasn't been pushed yet.
In other words: add and commit are local operations, push, pull and fetch are operations that interact with a remote.
Since there seems to be an official source control workflow in a place where you work, you should ask internally how this should be handled.
