+We already talked about using somebody else's work from a remote
+repository, in the "merging external work" section. It involved
+fetching the work from a remote repository; but how would _you_
+prepare a repository so that other people can fetch from it?
+Your real work happens in your working directory with your
+primary repository hanging under it as its ".git" subdirectory.
+You _could_ make it accessible remotely and ask people to pull
+from it, but in practice that is not the way things are usually
+done. A recommended way is to have a public repository, make it
+reachable by other people, and when the changes you made in your
+primary working directory are in good shape, update the public
+[ Side note: this public repository could further be mirrored,
+ and that is how kernel.org git repositories are done. ]
+Publishing the changes from your private repository to your
+public repository requires you to have write privilege on the
+machine that hosts your public repository, and it is internally
+done via an SSH connection.
+First, you need to create an empty repository to push to on the
+machine that houses your public repository. This needs to be
+Your private repository's GIT directory is usually .git, but
+often your public repository is named "<projectname>.git".
+Let's create such a public repository for project "my-git".
+After logging into the remote machine, create an empty
+Then, initialize that directory with git-init-db, but this time,
+since it's name is not usual ".git", we do things a bit
+ GIT_DIR=my-git.git git-init-db
+Make sure this directory is available for others you want your
+changes to be pulled by. Also make sure that you have the
+'git-receive-pack' program on the $PATH.
+[ Side note: many installations of sshd does not invoke your
+ shell as the login shell when you directly run programs; what
+ this means is that if your login shell is bash, only .bashrc
+ is read bypassing .bash_profile. As a workaround, make sure
+ .bashrc sets up $PATH so that 'git-receive-pack' program can
+Your 'public repository' is ready to accept your changes. Now,
+come back to the machine you have your private repository. From
+there, run this command:
+ git push <public-host>:/path/to/my-git.git master
+This synchronizes your public repository to match the named
+branch head (i.e. refs/heads/master in this case) and objects
+reachable from them in your current repository.
+As a real example, this is how I update my public git
+repository. Kernel.org mirror network takes care of the
+propagation to other publically visible machines:
+ git push master.kernel.org:/pub/scm/git/git.git/
