+# Calico
+
+Configure Calico components for the Master host.
+
+## Requirements
+
+* Ansible 2.2
+
+## Warning: This Calico Integration is in Alpha
+
+Calico shares the etcd instance used by OpenShift, and distributes client etcd certificates to each node.
+For this reason, **we do not (yet) recommend running Calico on any production-like
+cluster, or using it for any purpose besides early access testing.**
+
+## Installation
+
+To install, set the following inventory configuration parameters:
+
+* `openshift_use_calico=True`
+* `openshift_use_openshift_sdn=False`
+* `os_sdn_network_plugin_name='cni'`
+
+
+### Contact Information
+
+Author: Dan Osborne <dan@projectcalico.org>

+For support, join the `#openshift` channel on the [calico users slack](calicousers.slack.com).
