+## Mastaface -  A simple Facebook to Mastodon Bridge
 
 Mastaface scrapes the last post of a public facebook page and bridges it to mastodon.
 
 ## Features:
 - splits facebook posts with are longer than the character limit into serveral toots (replies)
 - checks only for the last post, so if you miss one, you're out of luck
-- only cross-posts the main-image of a facebook post
+- only cross-posts up to the first four images of a facebook post
 
 Please be sure to get the permission **before** mirroring some facebook site.
