-# auto
-
-*auto* enables serving zone data from an RFC 1035-style master file which is automatically picked
-up from disk.
-
-The *auto* middleware is used for an "old-style" DNS server. It serves from a preloaded file that exists
-on disk. If the zone file contains signatures (i.e. is signed, i.e. DNSSEC) correct DNSSEC answers
-are returned. Only NSEC is supported! If you use this setup *you* are responsible for resigning the
-zonefile. New zones or changed zone are automatically picked up from disk.
-
-## Syntax
-
-~~~
-auto [ZONES...] {
-    directory DIR [REGEXP ORIGIN_TEMPLATE [TIMEOUT]]
-    no_reload
-    upstream ADDRESS...
-}
-~~~
-
-**ZONES** zones it should be authoritative for. If empty, the zones from the configuration block
-are used.
-
-* `directory` loads zones from the speficied **DIR**. If a file name matches **REGEXP** it will be
-  used to extract the origin. **ORIGIN_TEMPLATE** will be used as a template for the origin. Strings
-  like `{<number>}` are replaced with the respective matches in the file name, i.e. `{1}` is the
-  first match, `{2}` is the second, etc.. The default is: `db\.(.*)  {1}` e.g. from a file with the
-  name `db.example.com`, the extracted origin will be `example.com`. **TIMEOUT** specifies how often
-  CoreDNS should scan the directory, the default is every 60 seconds. This value is in seconds.
-  The minimum value is 1 second.
-* `no_reload` by default CoreDNS will reload a zone from disk whenever it detects a change to the
-  file. This option disables that behavior.
-* `upstream` defines upstream resolvers to be used resolve external names found (think CNAMEs)
-  pointing to external names. **ADDRESS** can be an IP address, and IP:port or a string pointing to
-  a file that is structured as /etc/resolv.conf.
-
-All directives from the *file* middleware are supported. Note that *auto* will load all zones found,
-even though the directive might only receive queries for a specific zone. I.e:
-
-~~~
-auto example.org {
-    directory /etc/coredns/zones
-}
-~~~
-Will happily pick up a zone for `example.COM`, except it will never be queried, because the *auto*
-directive only is authoritative for `example.ORG`.
-
-## Examples
-
-Load `org` domains from `/etc/coredns/zones/org` and allow transfers to the internet, but send
-notifies to 10.240.1.1
-
-~~~
-auto org {
-    directory /etc/coredns/zones/org
-    transfer to *
-    transfer to 10.240.1.1
-}
-~~~
-
-Load `org` domains from `/etc/coredns/zones/org` and looks for file names as `www.db.example.org`,
-where `example.org` is the origin. Scan every 45 seconds.
-
-~~~
-auto org {
-    directory /etc/coredns/zones/org www\.db\.(.*) {1} 45
-}
