+.SH "DESCRIPTION"
+.sp
+The Firmware Image Download command is used to download all or a portion of the firmware image for a future update to the controller\&. The Firmware Image Download command may be submitted while other commands on the Admin Submission Queue or I/O Submission Queues are outstanding\&. The Firmware Image Download command copies the new firmware image (in whole or in part) to the controller\&.
+.sp
+The firmware image may be constructed of multiple pieces that are individually downloaded with separate Firmware Image Download commands\&. Each Firmware Image Download command includes a Dword Offset and Number of Dwords that specify a Dword range\&. The host software shall ensure that firmware pieces do not have Dword ranges that overlap\&. Firmware portions may be submitted out of order to the controller\&.
+.sp
+The new firmware image is not applied as part of the Firmware Image Download command\&. It is applied following a reset, where the image to apply and the firmware slot it should be committed to is specified with the Firmware Commit command (nvme fw\-commit <args>)\&.
+.SH "OPTIONS"
+.PP
+\-f <firmware\-file>, \-\-fw=<firmeware\-file>
+.RS 4
+Required argument\&. This specifies the path to the device\(cqs firmware file on your system that will be read by the program and sent to the device\&.
+.RE
+.PP
+\-x <transfer\-size>, \-\-xfer=<transfer\-size>
+.RS 4
+This specifies the size to split each transfer\&. This is useful if the device has a max transfer size requirement for firmware\&. It defaults to 4k\&.
+.RE
+.PP
+\-o <offset>, \-\-offset=<offset>
+.RS 4
+This specifies the starting offset in dwords\&. This is really only useful if your firmware is split in multiple files; otherwise the offset starts at zero and automatically adjusts based on the
+\fIxfer\fR
+size given\&.
