+# Ansible Role: ha-bridge-docker
+
+An Ansible role that manages ha-bridge Docker container with systemd on Raspbian and Debian OS.
+This role is compatible with OS version Stretch (9) and Jessie (8).
+
+## Requirements
+
+The Docker daemon should be already installed and running on the host side.
+I recommend using of the Ansible Galaxy role [angstwad.docker_ubuntu](https://github.com/angstwad/docker.ubuntu) to manage the Docker daemon.
+
+This role is tested with Ansible version greater equal 2.4.
+
+## Install
+
+```
+$ ansible-galaxy install escalate.ha-bridge-docker
+```
+
+## Role Variables
+
+Please see [defaults/main.yml](https://github.com/escalate/ansible-ha-bridge-docker/blob/master/defaults/main.yml) for a complete list of variables that can be overridden.
+
+## Dependencies

+## Example Playbook
+
+```
+- hosts: all
+  roles:
+    - escalate.ha-bridge-docker
