+## Xray/V2Ray Routing Setup
+Download the `iplist.dat` file into your working directory:
+```
+https://iplist.opencck.org/?format=geoip&data=cidr4
+```
+
+Example routing configuration:
+```json
+{
+  "routing": {
+    "rules": [
+      {
+        "type": "field",
+        "outboundTag": "vpn",
+        "ip": ["ext:iplist.dat"]
+      },
+      ...
+    ]
+  },
+  ...
+}
+```
+
+Example of using tags (by portal name or group) in the configuration:
+```json
+{
+  "routing": {
+    "rules": [
+      {
+        "type": "field",
+        "outboundTag": "vpn",
+        "ip": ["ext:iplist.dat:youtube.com"]
+      },
+      {
+        "type": "field",
+        "outboundTag": "vpn",
+        "ip": ["ext:iplist.dat:anime"]
+      },
+      ...
+    ]
+  },
+  ...
+}
+```
