 ## How To Use

-### Automated Installation
+⚠️ Please note: We welcome PR submissions from the community, but please submit your PRs to the [NTrace-V1](https://github.com/nxtrace/NTrace-V1) repository instead of [NTrace-core](https://github.com/nxtrace/NTrace-core) repository.<br>
+Regarding the NTrace-V1 and NTrace-core repositories:<br>
+Both will largely remain consistent with each other. All development work is done within the NTrace-V1 repository. The NTrace-V1 repository releases new versions first. After running stably for an undetermined period, we will synchronize that version to NTrace-core. This means that the NTrace-V1 repository serves as a "beta" or "testing" version.<br>
+Please note, there are exceptions to this synchronization. If a version of NTrace-V1 encounters a serious bug, NTrace-core will skip that flawed version and synchronize directly to the next version that resolves the issue.

 ## How To Use
 
+Document Language: [English](README.md) | 简体中文
+
+⚠️ 请注意：我们欢迎来自社区的PR提交，但是请将您的PR提交至 [NTrace-V1](https://github.com/nxtrace/NTrace-V1) 仓库，而不是 [NTrace-core](https://github.com/nxtrace/NTrace-core) 仓库。<br>
+关于NTrace-V1和NTrace-core两个仓库的说明：<br>
+二者将大体上保持一致。所有的开发工作均在NTrace-V1仓库中进行。NTrace-V1仓库首先发布新版本，在稳定运行一段时间后（时长不定），我们会把版本同步至NTrace-core。这意味着NTrace-V1仓库充当了一个“测试版”的角色。<br>
+请注意，版本同步也存在例外。如果NTrace-V1的某个版本出现了严重的bug，NTrace-core会跳过这一有缺陷的版本，直接同步到下一个修复了该问题的版本。
+
 ### Before Using
 
-使用 NextTrace 之前，我们建议您先阅读 [#IP 数据以及精准度说明](https://github.com/sjlleo/nexttrace/blob/main/README_zh_CN.md#ip-%E6%95%B0%E6%8D%AE%E4%BB%A5%E5%8F%8A%E7%B2%BE%E5%87%86%E5%BA%A6%E8%AF%B4%E6%98%8E)，在了解您自己的对数据精准度需求以后再进行抉择。

 NextTrace 有多个数据源可以选择，目前默认使用的 LeoMoeAPI 为我们项目维护的数据源。
 
+该项目由 OwO Network 的 [Missuo](https://github.com/missuo) && [Leo](https://github.com/sjlleo) 发起，由 [Zhshch](https://github.com/zhshch2002/) 完成最早期架构的编写和指导，后由 Leo 完成了大部分开发工作，现主要交由 [tsosunchia](https://github.com/tsosunchia) 完成后续的二开和维护工作。

+LeoMoeAPI 是 [Leo](https://github.com/sjlleo) 的作品，归属于 Leo Network，由 [Leo](https://github.com/sjlleo) 完成整套后端 API 编写，该接口未经允许不可用于任何第三方用途。

 LeoMoeAPI 早期数据主要来自 IPInsight、IPInfo，随着项目发展，越来越多的志愿者参与进了这个项目。目前 LeoMoeAPI 有近一半的数据是社区提供的，而另外一半主要来自于包含 IPInfo、IPData、BigDataCloud、IPGeoLocation 在内的多个第三方数据。
 
 LeoMoeAPI 的骨干网数据有近 70% 是社区自发反馈又或者是项目组成员校准的，这给本项目的路由跟踪基础功能带来了一定的保证，但是全球骨干网的体量庞大，我们并无能力如 IPIP 等商业公司拥有海量监测节点，这使得 LeoMoeAPI 的数据精准度无法和形如 BestTrace（IPIP）相提并论。

 我们不保证我们的数据一定会及时更新，也不保证数据的精确性，我们希望您在发现数据错误的时候可以前往 issue 页面提交错误报告，谢谢。

+## DN42 模式使用说明
+
+使用这个模式需要您配置 2 个文件，分别是 geofeed.csv 以及 ptr.csv
+
+当您初次运行 DN42 模式，NT 会为您生成 nt_config.yaml 文件，您可以自定义 2 个文件的存放位置，默认应该存放在 NT 的运行目录下
+
+### GeoFeed
+
+对于 geofeed.csv 来说，格式如下：
+```
+IP_CDIR,LtdCode,ISO3166-2,CityName,ASN,IPWhois
+```
+
+比如，您可以这么写：
+
+```
+58.215.96.0/20,CN,CN-JS,Wuxi,23650,CHINANET-JS
+```
+
+如果您有一个大段作为骨干网使用，您也可以不写地理位置信息，如下：
+
+```
+202.97.0.0/16,,,4134,CHINANET-BACKBONE
+```
+
+### PTR
+
+对于 ptr.csv 来说，格式如下：
+```
+IATA_CODE,LtdCode,RegionName,CityName
+```
+
+比如对于美国洛杉矶，您可以这么写
+
+```
+LAX,US,California,Los Anegles
+```
+
+需要注意的是，NextTrace 支持自动匹配 CSV 中的城市名，如果您的 PTR 记录中有 `losangeles`，您可以只添加上面一条记录就可以正常识别并读取。
