How to push local commits to online GitHub in Eclipse?

I found help for this issue from the link: https://wiki.eclipse.org/Git_and_EGit_for_Beginners

Following is an excerpt from the page:

In git, it(committing a change to the server) is a two step process. 1) You must COMMIT your changes at the file or folder level. This only commits them to a local git repository. To do the local commit, select the file, right-click menu, Team -> Commit. 2) To push them back to the server, you need to "Push to Upstream". You can only push to upstream at the project/repo level. You can't push an individual file, like you can in CVS.

To Push to Upstream, select the project/repo, select Team -> Push to Upstream.
