giddyup | Simple web application deployment with git push

At this stage, giddyup is only available directly as a git repo. There are no versioned releases, nor are there distribution packages available. My recommendation is to create a clone of the main giddyup repo somewhere (I suggest /usr/local/lib/giddyup if you've got root, and probably ~/giddyup otherwise) and then to update to newer giddyup functionality, just git pull in that clone. You then have a fixed location to point your hook symlinks and inclusions of functions.sh. Eventually, when giddyup stabilises there will be distribution packages; they'll likely put everything into /usr/lib/giddyup, at which time you can just delete your git repo at /usr/local/lib/giddyup and symlink that location /usr/lib/giddyup, and nothing else will need to change. Symlink the giddyup script to somewhere in your PATH; this will allow you to trivially setup new deployment destinations. Do not copy the giddyup script; it relies on being in the same directory as update-hook in order to be able to find the hook script.
Run the giddyup script, passing it the location of the "root" of your new deployment. The script will create the basic directory structure and symlink the update hook into the right place. Set the git config variables in the config for the repo you created in step 1 (see the section "Configuration" for the available variables). e.g. git config -f /home/appuser/appname/repo/config giddyup.environment production. Add the necessary hooks to your application's local git repo to effect proper deployment.

Add the newly created git repo as a remote in your local working copy, then push to that remote to make your initial deploy: e.g. git remote add deploy appuser@example.com:appname/repo; git push deploy master:master
Configure your webserver to pass requests to the appserver, and test that everything is working properly.
