-The tastiest way to work with Linux extended attributes (xattrs) written in pure Rust
+The tastiest way to manage data using Linux extended attributes (xattrs), written in pure Rust
 and made of delicious, fibrous Open Source code.
 
 Ghee provides tools for manipulating xattrs on individual files as well as for working with the filesystem as a document database
 where the filesystem paths act as primary keys and extended attributes act as fields.
 
-## History
+Data in Ghee tables can be managed using Git-style commits, implemented as Btrfs subvolumes and read-only snapshots.
 
-Ghee was developed in conjunction with the [Audiotater](https://git.disroot.org/joshhansen/audiotater) audio annotation tool.
+In this way Ghee leverages the copy-on-write (CoW) nature of Btrfs to efficiently store deltas, even on large binary blobs.
