 Apollo-11
 =========
 
+*Also available in: [English](README.md), [简体中文](README.zh_cn.md), [正體中文](README.zh_tw.md).*
+
 Original Apollo 11 guidance computer (AGC) source code for Command Module (Comanche055) and Lunar Module (Luminary099). Digitized by the folks at [Virtual AGC](http://www.ibiblio.org/apollo/) and [MIT Museum](http://web.mit.edu/museum/). The goal is to be a repo for the original Apollo 11 source code. As such, PRs are welcome for any issues identified between the transcriptions in this repository and the original source scans for [Luminary 099](http://www.ibiblio.org/apollo/ScansForConversion/Luminary099/) and [Comanche 055](http://www.ibiblio.org/apollo/ScansForConversion/Comanche055/), as well as any files I may have missed.
 ##Compilation
 If you are interested in compiling the original source code, check out [Virtual AGC](https://github.com/rburkey2005/virtualagc).

 这是起初，阿波罗11号指引计算机（AGC）用于驾驶舱（Comanche055）和登月舱（Luminary099）的源代码。其是由身处 [Virtual AGC](http://www.ibiblio.org/apollo/) 及 [MIT Museum](http://web.mit.edu/museum/) 的各位工作人员所抄录出来，目的在于建立一个用于存放阿波罗11号源码的项目。正因如此，若你在项目抄录或在查看 [Luminary 099](http://www.ibiblio.org/apollo/ScansForConversion/Luminary099/) 和 [Comanche 055](http://www.ibiblio.org/apollo/ScansForConversion/Comanche055/) 这两部分源代码的过程中，明确地遇到了问题的话，我们欢迎你能为之提起一个 PR。当然，也包括那些我可能会遗忘的文件。
