+# Cloudflare DDNS 更新脚本 for Openwrt/Lede
+
+## 依赖 
+
+- ddns-script
+
+## 教程
+
+如果你安装 ddns-script 在添加到供应商看到了 cloudflare 那就不需要本脚本了，如果没有看到那么接着往下看。
+
+先把本脚本 `cloudflare_ddns_update.sh` 上传只 openwrt 的 `/root` 目录下面。
+
+再从 Cloudflare 获取 Global API Key 备用（记作为 API_KEY），预先添加一个 A 记录，IP 随意写比如 127.0.0.1，
+添加后点击看下面的 API 能够从 APIs 链接获取到 Zone id（记作为 API_ZONE_ID），然后需要通过 curl 获取 dns records 
+列表接口查看刚才新添加的 A 记录的 DNS Record id（记作为 API_DNS_RECORD_ID）
+
+在 openwrt 的 ddns 添加出供应商选择 Custom，更新脚本填写 `/root/cloudflare_ddns_update.sh`，
+域名填写你的域名，用户名填写你的注册邮箱，密码填写 API_KEY，由于下面额外的参数没有搞懂怎么用，
+API_ZONE_ID 和 API_DNS_RECORD_ID 获取的值需要填写在脚本对应的变量后面。填写完成后点击保存并应用。
+
+最后点击启用并启动即可。你可以通过系统日志看到类似的日志就说明完成了！
