 ### TUN configuration
 Supports macOS, Linux and Windows.

-Support lwIP stack, a lightweight TCP/IP stack, recommend set to tun.
+Support lwIP stack, a lightweight TCP/IP stack, it's recommended set to tun.

 On Windows, you should download the [Wintun](https://www.wintun.net) driver and copy `wintun.dll` into Clash home directory.
 ```yaml
 # Enable the TUN listener
 tun:
  enable: true
-  stack: lwip # lwip(recommend), system or gvisor
+  stack: lwip # lwip(recommended), system or gvisor
  dns-listen: 0.0.0.0:53 # additional dns server listen on TUN
  auto-route: true # auto set global route
 ```
 ### Rules configuration
 - Support rule `GEOSITE`.
+- Support rule `SCRIPT`.
 - Support `multiport` condition for rule `SRC-PORT` and `DST-PORT`.
- Support not match condition for rule `GEOIP`.
 - Support `network` condition for all rules.
 - Support source IPCIDR condition for all rules, just append to the end.

-The `GEOSITE` and `GEOIP` databases via https://github.com/Loyalsoldier/v2ray-rules-dat.
