 ## zone**
+The basic format is `<dns path>: { <record type>: [<value>, <value>] }`
+It is possible to do short hand notations:
+
+* If there is only a single value for an entry, you can omit the array and use ``<dns path>: { <record type>: <value> }`
+* YAML anchors and merges are recommend for situations where a `CNAME` is not possible
+* You can use hierachy to shorten paths. If you have `foo.example.com` and 'bar.example.com' you could write
 ```
+"example.com.":
+	foo:
+		A: 1.1.1.1
+	bar:
+		A: 1.1.1.1
+```
+
+For the `SOA` record, `##sequence##` is replaced by a generated sqeuence number.
+
+Example for a zone:
+```
+"example.de":
+	SOA: "ns.example.de zonefile.example.de ##sequence## 1d 2h 4w 1h"
+	CAA: 0 issue "letsencrypt.org"
+
+	NS:
+		- ns0.example.de
+		- ns1.example.de
+
+	ns:
+		CNAME: ns0.example.de.
+
+	ns0:
+		A: 1.1.1.1
+		AAAA: ::5
+
+	git:
+		A:
+			- 2.2.2.2
+			- 3.3.3.3
+		AAAA: ::6
