To share your code you create a repository on a remote server to which you will copy your local repository.
To minimize the use of space on the remote server you create a bare repository: one which has only the
.git objects and doesn't create a working copy in the filesystem. As a bonus you set this remote as an upstream server to easily share updates with other programmers.
On the remote server:
git init --bare /path/to/repo.git
On the local machine:
git remote add origin ssh://username@server:/path/to/repo.git
ssh: is just one possible way of accessing the remote repository.)
