+- `Release`里面为很多系统以及不同架构提供了编译好的二进制可执行文件，如果没有可以自行编译。
+- 一些本项目的必要依赖在`Windows`上`Golang`底层实现不完全，所以目前`NextTrace`在`Windows`平台不可用。

-### IP数据库
+`NextTrace`也同样支持一些进阶功能，如 IP 反向解析、并发数控制、模式切换等
 
-目前使用的IP数据库默认为我们自己搭建的API服务，如果后期遇到滥用，我们可能会选择关闭。
+```bash
+# 每一跳发送2个探测包
+nexttrace -q 2 www.hkix.net
 
-我们也会在后期开放服务端源代码，您也可以根据该项目的源码自行搭建属于您的API服务器。

+`NextTrace`支持用户自主选择 IP 数据库（目前支持：`LeoMoeAPI`, `IP.SB`, `IPInfo`, `IPInsight`, `IPAPI.com`）
+
+```bash
+# 可以自行指定IP数据库[此处为IP.SB]，不指定则默认为LeoMoeAPI
+nexttrace -d IP.SB
+## 特别的：其中 ipinfo API 需要从ipinfo自行购买服务，如有需要可以clone本项目添加其提供的token自行编译
+##        TOKEN填写路径：ipgeo/tokens.go
+## 另外：由于IP.SB被滥用比较严重，会经常出现无法查询的问题，请知悉。
+##      IPAPI.com限制调用较为严格，如有查询不到的情况，请几分钟后再试。
+```
+
+`NextTrace`支持参数混合使用
+
+```bash
+Example:
+nexttrace -d IPInsight -m 20 -p 443 -q 5 -r 20 -rdns 1.1.1.1
+nexttrace -T -q 2 -r 1 -rdns -table -report 2001:4860:4860::8888
