+ntfs-efi
+---------
+
+btrfs-efi is an NTFS filesystem driver for EFI. It is intended for use with the free
+Windows bootloader [Quibble](https://github.com/maharmstone/quibble), but you
+should be able to use it for anything EFI-related.
+
+Thanks to [Eric Biggers](https://github.com/ebiggers), who [successfully reverse-engineered](https://github.com/ebiggers/ntfs-3g-system-compression/) Windows 10's
+"WOF compressed data", and whose code I've used here.
