-An simply __process manager__ wrapper API for **PHP** to _execute_ and _manage_ **sub-processes**.
+An simply __`uv_spawn`__ wrapper API to _execute_ and _manage_ **sub-processes**, parallel/asynchronous PHP for Blocking I/O.
 
 This package uses features of [`libuv`](https://github.com/libuv/libuv), the PHP extension [UV](https://github.com/bwoebi/php-uv), of the  **Node.js**  library. It's `uv_spawn` function is used to launch processes. The performance it a much better alternative to pcntl-extension, or the use of `proc_open`. The package will fallback to use [symfony/process], if `libuv` is not installed.
