 ## How it works
+It will download the last version of every file present on Wayback Machine to `./websites/example.com/`. It will also re-create a directory structure and auto-create `index.html` pages to work seamlessly with Apache and Nginx. All files downloaded are the original ones and not Wayback Machine rewritten versions; this way, URLs and links structure are the same as before.
