 注意：
 
-- 当前 `Auto` 按钮只负责 DuckDuckGo 地址获取
+- 若 `邮箱生成 = Cloudflare`，插件里只需要维护 `CF 域名`
+- `CF 域名` 支持保存多个，并通过下拉框切换当前要生成的域名
+- Cloudflare 侧的转发规则、Catch-all、路由目标邮箱等，都需要你自己提前在 Cloudflare 后台配置好
 - 如果你使用 Inbucket，它只是验证码收件箱，不会自动生成 Inbucket 地址
 
+### `邮箱生成 = Cloudflare` 时的配置
+
+- `CF 域名`：例如 `example.xyz`
+- 右侧 `添加 / 保存`：用于保存多个可切换的域名
+- 下拉框：用于切换当前这次要生成邮箱所使用的域名
+
+#### 当前实现是什么逻辑
+
+Cloudflare 模式下，插件不会再调用 Cloudflare API 创建路由。
+
+它现在只做一件事：
+
+1. 根据你当前选中的 `CF 域名`
+2. 本地生成一个随机前缀
+3. 直接得到一个类似 `user20260412153000123@example.xyz` 的注册邮箱
+4. 把这个邮箱写入当前流程继续往下跑
+
+也就是说，插件默认认为：
+
+- 你已经在 Cloudflare 后台把这个域名的收件转发规则配置好了
+- 这个随机前缀邮箱发来的邮件，最终能被你现有的 `163 / QQ / Inbucket` 收件链路接住
+
+#### 你需要自己提前做什么
+
+在 Cloudflare 后台，至少保证下面一条成立：
+
+- 你已经配好了 Catch-all / 通配规则，能接住任意前缀邮箱
+- 或者你本来就有一套能覆盖这些随机前缀邮箱的转发规则
+
+否则插件虽然能生成 `@你的域名` 邮箱，但验证码邮件最后没人接收，后面的 Step 4 / Step 7 还是会失败。
+
+#### 最简单的使用方式
+
+1. 在 Cloudflare 后台先把你的域名收件转发规则配好
+2. 在插件里选择 `邮箱生成 = Cloudflare`
+3. 在 `CF 域名` 里点 `添加`
+4. 输入域名后点 `保存`
+5. 以后直接从下拉框切换当前使用的域名
+6. 点击 `获取`，插件就会基于这个域名生成一个随机邮箱
