 Packages managed entirely by Composer do not *need* to contain any
 `.bat` files for Windows compatibility. Composer handles installation
 of binaries in a special way when run in a Windows environment:
 
+完全由 Composer 管理的包并不*需要*包含任何用以兼容 Windows 的
+`.bat`文件。在 Windows 环境下运行时，Composer 会用一种特殊的方式处理
+二进制文件的安装：

  * A `.bat` file is generated automatically to reference the binary
  * A Unix-style proxy file with the same name as the binary is generated
    automatically (useful for Cygwin or Git Bash)
 
+ * 一个用以引用此二进制文件的 `.bat` 文件会自动生成
+ * 一个与该二进制文件同名的 Unix-风格的代理文件也会自动生成

+
 Packages that need to support workflows that may not include Composer
 are welcome to maintain custom `.bat` files. In this case, the package
 should **not** list the `.bat` file as a binary as it is not needed.
 
+若某包存在不涉及 Composer 的工作流程，
+那么它也可以维护一些定制的 `.bat` 文件。这种情况下，该包
+**不**应该把它们作为二进制文件罗列，因为 Composer 不需要知道它们。
 
-## Can vendor binaries be installed somewhere other than vendor/bin?
 
-Yes, there are two ways an alternate vendor binary location can be specified:
+## vendor binaries 可以安装在不是 vendor/bin 的地方么？
 
- 1. Setting the `bin-dir` configuration setting in `composer.json`
- 1. Setting the environment variable `COMPOSER_BIN_DIR`
+当然，这里有两种指定 vendor binary 的其他可选位置的方法：
 
-An example of the former looks like this:
+ 1. 在 `composer.json` 文件中的 `bin-dir` 配置属性处设置
+ 1. 设置环境变量 `COMPOSER_BIN_DIR`
