-           This is the integrity target.
+          This device-mapper target emulates a block device that has
+          additional per-sector tags that can be used for storing
+          integrity information.
+
+          This integrity target is used with the dm-crypt target to
+          provide authenticated disk encryption or it can be used
+          standalone.
+
+          To compile this code as a module, choose M here: the module will
+          be called dm-integrity.
