+RGW Multisite (Experimental)
+============================
+
+Directions for configuring the RGW Multisite support in ceph-ansible
+
+## Requirements
+
+* At least 2 Ceph clusters
+* 1 RGW per cluster
+* Jewel or newer
+
+More details:
+
+* Can configure a Master and Secondary realm/zonegroup/zone on 2 separate clusters.
+
+
+## Configuring the Master Zone in the Primary Cluster
+
+This will setup the realm, zonegroup and master zone and make them the defaults. It will also reconfigure the specified RGW for use with the zone.
+
+1. Edit the Inventory File
+
+```
+[rgws]
+cluster0-rgw0 rgw_zone=us-east rgw_zonemaster=true
+```
+1. Generate System Access and System Secret Keys
+
+```
+echo system_access_key: $(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 20 | head -n 1) > multi-site-keys.sh
+echo system_secret_key: $(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 40 | head -n 1) >> multi-site-keys.sh
+```
+1. Edit the RGW Group Vars
+
+```
+copy_admin_key: true
+# Enable Multisite support
+rgw_multisite: true
+rgw_realm: gold
+rgw_zonegroup: us
+system_access_key: 6kWkikvapSnHyE22P7nO
+system_secret_key: MGecsMrWtKZgngOHZdrd6d3JxGO5CPWgT2lcnpSt
+```
+
+**Note:** replace the system_access_key and system_secret_key values with the ones you generated
+
+1. Run the ceph-ansible playbook on your 1st cluster
+
+Note: If you have already installed a cluster with ceph-ansible, you can use the `rgw-configure.yml` playbook as a shortcut (Only runs the ceph-rgw role)
+
+## Configuring the Secondary Zone in a Separate Cluster
+
+```
+[rgws]
+cluster1-rgw0 rgw_zone=us-west rgw_zonesecondary=true
+```
+
+1. Edit the RGW Group Vars
+
+```
+copy_admin_key: true
+# Enable Multisite support
+rgw_multisite: true
+rgw_realm: gold
+rgw_zonegroup: us
+rgw_pullhost: cluster1-rgw0.fqdn
+system_access_key: 6kWkikvapSnHyE22P7nO
+system_secret_key: MGecsMrWtKZgngOHZdrd6d3JxGO5CPWgT2lcnpSt
+```
+
+**Note:** pullhost should be the host of the RGW that is configured as the Zone Master
+**Note:** system_access_key and system_secret_key should match what you used in the 1st cluster
+
+
+1. Run the ceph-ansible playbook on your 2nd cluster
+
+Note: If you have already installed a cluster with ceph-ansible, you can use the `rgw-configure.yml` playbook as a shortcut (Only runs the ceph-rgw role)
+
+## Conclusion
+
+You should now have a master zone on cluster0 and a secondary zone on cluster1 in an Active-Active mode.
