+Windows NT NTFS support (read only)
+CONFIG_NTFS_FS
+  NTFS is the file system of Microsoft Windows NT. Say Y if you want
+  to access partitions using this file system. The Linux NTFS driver
+  supports most of the mount options of the VFAT driver, see
+  Documentation/filesystems/ntfs.txt. There is an experimental
+  write support available; use at your own risk.
+
+NTFS read-write support (experimental)
+CONFIG_NTFS_RW
+  The read-write support in NTFS is far from being complete and well
+  tested. If you enable this, be prepared to recover the NTFS volume
+  from tape.
