+## Habitat Service Package for CHIME
+This package can be used to run CHIME as a fully self-contained application.
+See https://habitat.sh for more details.
+
+### Examples
+Quickstart With Docker "Shim" Container:
+```
+docker run -it -p 8000:8000 bixu/hab hab sup run "bixu/chime" --channel="unstable"
+```
+
+Local Prototyping Example:
+```
+set -e
+curl --silent "https://raw.githubusercontent.com/habitat-sh/habitat/master/components/hab/install.sh" | sudo bash -s
+hab cli setup
+direnv allow
+hab studio enter
+build
+hab sup run $HAB_ORIGIN/chime --channel="unstable"
+```
+
+Complete `systemd` Bootstrap Example:
+```
+echo 'HAB_AUTH_TOKEN="<enter your token from https://bldr.habitat.sh/#/profile>"
+HAB_LICENSE="accept"
+HAB_NONINTERACTIVE="true"
+' > supervisor.env
+
+echo '[Unit]
+Description=Habitat Supervisor

+EnvironmentFile=/etc/systemd/supervisor.env
+ExecStartPre=/bin/bash -c "/bin/systemctl set-environment SSL_CERT_FILE=$(hab pkg path core/cacerts)/ssl/cert.pem"
+ExecStart=/bin/hab sup run --no-color
+ExecStop=/bin/hab sup term
+KillMode=process
+Restart=on-failure
+[Install]

+sudo chown root "/etc/systemd/supervisor.env"
+sudo chmod 400 "/etc/systemd/supervisor.env"
+sudo mv supervisor.service "/etc/systemd/system/supervisor.service"
+sudo --preserve-env hab pkg install "core/hab-sup"
