 # 特性
 - DNS 服务器选用腾讯和阿里的公共 DNS，你也可以在 AdGuardHome 的 DNS 设置里更改来满足你的需求
 - 仅内置[秋风广告规则](https://github.com/TG-Twilight/AWAvenue-Ads-Rule)，精准，轻量，少误杀
-- 在 Magisk/KernelSU 中可以通过模块开关实时启动/关闭模块
+- 在 Magisk/KernelSU 中可以通过模块开关实时启动/关闭模块，当然你也可以在shell中模拟模块开关
+```shell
+touch /data/adb/modules/AdguardHome/disable
+```
 - 可修改位于 `/data/adb/agh/scripts/config.sh` 的配置文件来调整配置
-- 覆盖安装时会自动给原模块创建备份
+- 在更新模块时，用户可自行选择是否保留原来的配置文件，即使你选择不保留，也会自动备份原来的配置文件到 `/data/adb/agh/backup` 目录下
 
 # FAQ
-> Q: 为什么模块无法屏蔽某些广告?
+> Q: 为什么模块无法屏蔽全部广告?
 
-> A: 模块通过转发 53 端口的 DNS 请求来实现广告屏蔽，因此无法屏蔽通过 HTTPS 传输的广告，以及与正常内容同域名的广告，如 知乎，Youtube 等
+> A: 模块通过转发 53 端口的 DNS 请求来实现广告屏蔽，因此无法屏蔽通过 HTTPS 传输的广告，以及与正常内容同域名的广告，如 知乎，Youtube 等，好在大部分广告还是优先使用 53 端口的 DNS 请求。
 
-> Q: 为什么装上模块后访问页面变慢?
-
-> A: 因为模块会将所有 DNS 请求转发到 AdGuardHome，再由 AdGuardHome 转发到上游的公共 DNS，中间多了一层转发，但模块默认开启了乐观缓存，在第二次访问时将大大减少延迟
+> Q: 模块可以与其它代理模块/软件一起使用吗?
 
-> Q: 为什么本来可以访问的页面一段时间后出现了无法访问?
+> A: 可以，一般的代理app可以直接兼容(这里推荐使用[FlClash](https://github.com/chen08209/FlClash))，且 AdGuardHome 的 DNS 查询会经过 VPN，其它代理模块看情况使用，可关闭自动 iptables 规则当作普通 DNS 使用
 
-> A: 由于公共 DNS 请求较慢，模块默认配置文件里开启了乐观缓存，可能导致一些过时的 IP 在过期后仍然被使用，可在后台清理DNS缓存来缓解，或者关闭乐观缓存
+> Q: 为什么不接入 KernelSU 的 WebUI?
 
-> Q: 模块可以与其它代理模块/软件一起使用吗?
+> A: 由于 KernelSU 的 WebUI 在无法显示确认弹窗，导致 AdGuardHome 管理端一些功能无法使用，因此暂时不接入
 
-> A: 可以，一般的代理app可以直接兼容，且 AdGuardHome 的 DNS 查询会经过 VPN，其它代理模块看情况使用，可关闭自动 iptables 规则当作普通 DNS 使用

 # Features
 - The DNS server uses Tencent and Alibaba's public DNS, you can also change it in the DNS settings of AdGuardHome to meet your needs.
 - Only built-in [Autumn Breeze Ad Rule](https://github.com/TG-Twilight/AWAvenue-Ads-Rule), accurate, lightweight, and low false positives.
-- In Magisk/KernelSU, you can start/stop the module in real-time through the module switch.
+- In Magisk/KernelSU, you can start/stop the module in real-time using the module switch, or you can simulate the module switch in the shell.
+```shell
+touch /data/adb/modules/AdguardHome/disable
+```
 - You can modify the configuration file located in `/data/adb/agh/scripts/config.sh` to adjust the configuration.
-- When overwriting installation, the original module will be automatically backed up.
+- When updating the module, users can choose whether to keep the original configuration file, even if you choose not to keep it, the original configuration file will be automatically backed up to the `/data/adb/agh/backup` directory.
 
 # FAQ
-> Q: Why can't the module block some ads?
+> Q: Why can't the module block all ads?
 
-> A: The module blocks ads by forwarding DNS requests on port 53, so it cannot block ads transmitted over HTTPS or ads on the same domain as normal content, such as Zhihu, Youtube, etc.
+> A: The module blocks ads by forwarding DNS requests on port 53, so it cannot block ads transmitted over HTTPS or ads on the same domain as normal content, such as Zhihu, Youtube, etc., but fortunately, most ads still prefer to use DNS requests on port 53.
 
-> Q: Why does the page slow down after installing the module?
-
-> A: Because the module forwards all DNS requests to AdGuardHome, which then forwards them to the upstream public DNS, adding an extra layer of forwarding, but the module has optimistic caching enabled by default, which greatly reduces latency on the second visit.
-
-> Q: Why can't I access a page that I could access before after a while?
+> Q: Can the module be used with other proxy modules/software?
 
-> A: Because public DNS requests are slow, the module's default configuration file has optimistic caching enabled, which may cause some outdated IPs to continue to be used after they expire, you can clear the DNS cache in the background to alleviate this, or disable optimistic caching.
+> A: Yes, general proxy apps can be directly compatible (here we recommend using [FlClash](https://github.com/chen08209/FlClash)), and AdGuardHome's DNS queries will pass through the VPN, other proxy modules can be used as needed, and the automatic iptables rules can be turned off for normal DNS use.
 
-> Q: Can the module be used with other proxy modules/software?
+> Q: Why not integrate with KernelSU's WebUI?
 
-> A: Yes, general proxy apps are directly compatible, and AdGuardHome's DNS queries will pass through the VPN, other proxy modules can be used as needed, you can disable automatic iptables rules to use it as a regular DNS.
+> A: Because KernelSU's WebUI cannot display confirmation pop-ups, some functions of AdGuardHome's management end cannot be used, so it is not integrated for the time being.
