+	A provisioning script for initializing a bare-metal server. This runs
+	from the the new machine, expects to have shell and sudo access, and
+	handles initial setup before handing off to \`bootstrap.sh\`. Installs
+	git, clones the specified repo and starts provisioning using the
+	specified APP_ENV value.
+
+Usage:
+	From the machine to be provisioned:
+
+	curl https://raw.githubusercontent.com/loadsys/CakePHP-Shell-Scripts/master/${0##*/} | bash -s -- <REPO_CLONE_URL> <GIT_BRANCH> <APP_ENV_VALUE>
+
+	Should be run as the user the app will run as on the target server.
