 ```
 
+You should not fill in all of these, only use what is necessary. A typical example would look like:
+
+```
+{
+    {
+      "provider": "duckdns",
+      "username": "your-token",
+      "hostname": "sub.duckdns.org"
+    }
+  ]
+}
+```
+
+or:
+
+```
+{
+  "providers": [
+    {
+      "provider": "someprovider",
+      "username": "username",
+      "password": "password",
+      "hostname": "your.domain.com"
+    }
+  ]
+}
+```
+
+for a custom provider that is not supported by inadyn you can do:
+```
+{
+  "providers": [
+    {
+      "provider": "arbitraryname",
+      "username": "username",
+      "password": "password",
+      "hostname": "your.domain.com",
+      "ddns_server": "api.cp.easydns.com",
+      "ddns_path": "/somescript.php?hostname=%h&myip=%i",
+      "custom_provider": true
+    }
+  ]
+}
+```
+
+the tokens in ddns_path are outlined in the `inadyn.conf(5)` man page.
