 ## Configuration Reference
 
 Optional parameters:
 
 - `checksum_types` (array of strings) - An array of strings of checksum types
-  to compute. Allowed values are md5, sha1, sha224, sha256, sha384, sha512.
-
-- `keep_input_artifact` (boolean) - Unlike most post-processors, setting
-  `keep_input_artifact` will have no effect; the checksum post-processor
-  always saves the artifact that it is calculating the checksum for.
+  to compute. If empty, Defaults to md5. Allowed values are:
+  * md5
+  * sha1
+  * sha224
+  * sha256
+  * sha384
+  * sha512
 
 - `output` (string) - Specify filename to store checksums. This defaults to
   `packer_{{.BuildName}}_{{.BuilderType}}_{{.ChecksumType}}.checksum`. For
