 ### A note on Window's console
 
-If you plan to use vt-cli in Windows on a regular basis we highly recommend you to avoid the standard Windows's console and use Cygwin(https://www.cygwin.com/) instead. The Windows's console is *very* slow when printing large amounts of text (as vt-cli usually does) while Cygwin performs much better. Additionally you can benefit of Cygwin's support for command auto-completion, a handy feature that Window's console doesn't offer. In order to take advantage of auto-completion make sure to include the `bash-completion` package while installing Cygwin.
