+# Usage of Domain Set
+
+To facilitate configuring domain names by collection, the domain set can be specified for configuration with `/domain/`. The specific method is:
+
+1. Use `domain-set` to configure the collection file, such as:
+
+    ```shell
+    domain-set -name ad -file /etc/smartdns/ad-list.conf
+    ```
+
+    The format of `ad-list.conf` is one domain per line, such as:
+
+    ```shell
+    ad.com
+    site.com
+    ```
+
+2. Use the domain set in the options with `/domain/` configuration. Just set `/domain/` to `/domain-set:[collection name]/`, such as:
+
+    ```shell
+    address /domain-set:ad/#
+    domain-rules /domain-set:ad/ -a #
+    nameserver /domain-set:ad/server
+    ```
