About

This project is an open-source component of i18n.site ⋅ Internationalization Solution.

• i18 : MarkDown Command Line Translation Tool

  The translation perfectly maintains the Markdown format.

  It recognizes file changes and only translates the modified files.

  The translated Markdown content is editable; if you modify the original text and translate it again, manually edited translations will not be overwritten (as long as the original text has not been changed).

• i18n.site : MarkDown Multi-language Static Site Generator

  Optimized for a better reading experience

关于

本项目为 i18n.site ⋅ 国际化解决方案 的开源组件。

• i18 : MarkDown命令行翻译工具

  翻译能够完美保持 Markdown 的格式。能识别文件的修改，仅翻译有变动的文件。

  Markdown 翻译内容可编辑；如果你修改原文并再次机器翻译，手动修改过的翻译不会被覆盖（如果这段原文没有被修改）。

• i18n.site : MarkDown多语言静态站点生成器 为阅读体验而优化。
