-## 简介
+## Introduction
 
-Atom 是一个免费、开源、跨平台的文本编辑器，由 GitHub 开发。它是用 JavaScript 编写的，并且采用 Electron 架构。它的一个较大缺点就是性能差。
+Atom is a free and open-source cross-platform text editor developed by Github. It is written in Javascript and based on Electron. A relatively larger disadvantage is bad performance.

-## 介绍
+## Introduction
 
-> Dev-C++ 是一套用于开发 C/C++（C++11）的自由的集成开发环境（IDE），并以 GPL 作为散布许可。使用 MinGW 及 GDB 作为编译系统与调试系统。Dev-C++ 的 IDE 是利用 Delphi 开发的。
->
-> Dev-C++ 是一个 SourceForge 的项目，是由 Colin Laplace 这位程序员及其公司 Bloodshed Software 所开始的。当前 Dev-C++ 一般用于撰写运行于 Microsoft Windows 的程序。Dev-C++ 一度有移植到 Linux 的项目但当前被暂停了。
->
-> Bloodshed Dev-C++ 是一款全功能的 C 和 C++ 编程语言的集成开发环境（IDE）。它使用的 GCC MinGW 或 TDM-GCC 的 64 位版本作为它的编译器。Dev-C++ 也可以使用 Cygwin 或任何其他基于 GCC 编译器组合使用。
->
-> 此外，Dev-C++ 较旧的版本无法在 win8 环境下编译。
->
-> 该项目已不再明显活跃，从 2005 年 2 月 22 日开始至 2011 年 6 月，Dev-C++ 的官方网站一直没有再发出新消息或是释放新版本，说明 Dev-C++ 的开发已经进入了迟滞状态。2006 年，Dev-C++ 主要开发者 Colin Laplace 曾经对此作出了解释：“因忙于现实生活的事务，没有时间继续 Dev-C++ 的开发。”
+Dev-C++ is a free full-featured integrated development environment (IDE) distributed under the GNU General Public License for programming in C and C++(including C++11 and later). It is bundled with, and uses, the MinGW and GDB as its compiler and debugger. Dev-C++ runs in Microsoft Windows.
 
-以上摘自 Wikipedia[^1]。
+The advantage of Dev-C++ is friendly user interface, simple installation and support single file compilation. Therefore, it becomes the first choice of many beginner C++ learners and beginner competitors of competitive programming. For NOIP, in provinces which offer Windows as a standard operation system, it generally comes with pre-installed Dev-C++.
 
-不过，你在使用的版本是不是我说的这个版本呢？
+The origin of Dev-C++ is Bloodshed Dev-C++ written by Colin Laplace. From February 22, 2005, the project was stopped updating. In 2006 lead developer Colin Laplace stated for the situation that he was busy with real-life issues and did not have time to continue development of Dev-C++.
 
-没错，Dev-C++ 其实还有一个全新版本：
+Orwell Dev-C++ is a variant of Bloodshed Dev-C++, developed and maintained by individual programmer Orwell (Johan Mes). The variant contains bug fixes and updates for compiler. Generally speaking, all Dev-C++ 5.x are Orwell Dev-C++. The variant was last updated in 2015 with version number 5.11.
 
-> Orwell Dev-C++ 是 Dev-C++ 的一个衍生版本。Orwell 鉴于 Dev-C++ 的长时间（从 2005 年 2 月 22 日起）不再更新，对 Dev-C++ 源代码进行错误修正，并更新编译器后发布的版本。
+Embarcadero Dev-C++[^ref1] is a successor of Bloodshed Dev-C++ and Orwell Dev-C++. In 2020, Embarcadero sponsored and continued the development of original Bloodshed Dev-C++. It contains support for high DPI, updates of compiler, support for updated version of C++ standard and dark mode.
 
-以上摘自 Wikipedia[^2]。
+The Dev-C++ distributions listed above are considered "official releases". Besides, after the stale development Orwell Dev-C++ in 2015, out of the need of teaching, an individual Chinese developer [royqh1979](https://github.com/royqh1979) decided to develop his personal fork of Dev-C++ named "Red Panda Dev-C++", integrating intelligent hint and updated version of MINGW64, which is convenient for personal use and studying. The project is hosted on [GitHub](https://github.com/royqh1979/Dev-Cpp).
 
-自 2011 年的 Dev-C++ 4.9.9.3 版本之后，你使用的版本均为 Orwell Dev-C++。

-在 2015 年停止更新后，因为教学需要，一位来自中国的个人开发者 [royqh1979](https://github.com/royqh1979) 决定继续开发他的 Dev-C++ 个人分支，命名为小熊猫 Dev-C++，集成了智能提示和高版本的 MINGW64，非常便于国内的个人使用和学习，项目官网位于 [小熊猫 Dev-C++](https://royqh.net/devcpp/download)，源码地址位于 [Github](https://github.com/royqh1979/Dev-Cpp).

-#### 生成调试信息
+#### Generate Debugging Informations
 
-当显示 "项目没有调试信息，您想打开项目调试选项并重新生成吗？" 点击后闪退或想使用调试功能时需开启此功能。
+This option is needed when the user clicks "Debug" and the editor pops up a window "You have not enabled debugging info (-g) and/or stripped it from the executable (-s) in Compiler Options" and it crashed after the user clicked "Yes", or the user wants the debugging feature to be always-on.

+Click "Tools" -> "Compiler Options...", and select the tab "General". Below are some frequently used tricks.
 
-#### 开大栈
+#### Extend the Stack
 
-防止 DFS 爆系统栈之类的情况出现。
+This may prevent stack overflow caused by too many recursions (like depth-first search).
 
-在 "连接器命令行加入以下命令" 中加入 `-Wl,--stack=128000000` 命令。
+Add `-Wl,--stack=128000000` to "Add the following commands when calling the linker".
 
-此命令将栈开到了约 128MB 的大小，有需要可以自行增加。
+The example above resized the stack to approximately 128MB, and can be adjusted if needed.

-#### 定义宏
-
-方便本地评测使用文件输入输出或作其他用途。
+#### Define Marco
 
-在 "连接器命令行加入以下命令" 中加入 `-D[String]` 命令。
+Macro is useful when testing locally with file I/O or other purposes.

-其中 `[String]` 改为你需要的宏名。
+Add `-D[string]` to "Add the following commands when calling the linker", where `[string]` is the macro needed to define.
 
-如图，当开启编译选项后便可将以下代码从 `test.in` 文件读入数据并在 `test.out` 文件中输出。
+In the following example, the parameter `-DLOCAL` make the following code to read from the file `test.in` and print to file `test.out`. <!---Which means, without the parameter the following code won't be compiled.-->
