Host Your Own Remote Repository

If you want to set up a private git repository on your own server, here's how you'd do it. You'll need SSH access to follow along.

ssh user@host.com
mkdir -p git/octopress.git
cd git/octopress.git
git init --bare
pwd  # print the working directory, you'll need it below.
logout

The url for your remote repository is ssh://user@host.com/(output of pwd above)
