Bare repository in Git is a repository which only contains version control information only in fact this will not have .git sub-directory or any working files.
This kind of repository is helpful when you need to share or divide your work between few people for example in work environment you and your team mates are working on same project and you all need to see changes and all needs to do push to repository in this case this repository is more useful.
You can add the remote repository to local git repo
$ git remote add origin ssh://myserver.com/var/git/myapp.git
pushing to remote repository:
to push our local master branch to the origin's master branch. You can do that using the git push <target> <local>
command.
$ git push origin master
