 ### File types
 
-Currently supported file types are:
+`dotnet-srcset` uses [ImageSharp](https://imagesharp.net) under the hood, and therefore should theoretically support all file types that ImageSharp supports by entering the filename as a parameter, however when entering a directory as a parameter, file types are limited to:
 
 - jpg/jpeg
 - png
 - bmp
-- gif _(not animated)_
