# HF Transfer

Speed up file transfers with the Hub.


This library is a power user tool, to go beyond `~500MB/s` on very high bandwidth
network, where Python cannot cap out the available bandwidth.

This is *not* meant to be a general usability tool.
It purposefully lacks progressbars and comes generally as-is.

Please file issues *only* if there's an issue on the underlying downloaded file.
