+## CloudFlare DNS
+
+Rancher External DNS service powered by CloudFlare DNS
+
+#### Changelog
+
+##### v0.6.0
+
+* Reduces the overall rate of API requests to the DNS provider
+* Adds support for custom DNS naming convention
+* Stack, service and environment names used in service DNS names are now sanitized to conform with RFC 1123. Characters other than `a-z`, `A-Z`, `0-9` or `dash` are replaced by dashes.
+* For internal use the service creates TXT records to track the FQDNs it manages. These TXT records are named `external-dns-<environemntUUID>.<domain>` and should not be deleted.
+
+#### Usage
+
+##### Upgrade Notes
+While upgrading from a version lower than v0.6.0 the TTL configuration value should not be changed. You may change it once the upgrade has been completed.
+
+##### Limitation when running the service on multiple Rancher servers
+
+When running multiple instances of the External DNS service configured to use the **same** domain name, then only one of them can run in the "Default" environment of a Rancher server instance.
+
+##### Custom DNS name template
+
+By default DNS entries are named `<service>.<stack>.<environment>.<domain>`.    
+You can specify a custom name template used to construct the subdomain part (left of the domain name) of the DNS records. The following placeholders are supported:
+
+* `%{{service_name}}`
+* `%{{stack_name}}`
+* `%{{environment_name}}`
+
+**Example:**
+
+`%{{stack_name}}-%{{service_name}}.statictext`
+
+Make sure to only use characters in static text and separators that are allowed by your provider in DNS names.
