 uefi-md5sum - MD5 checksum validation for UEFI
 ==============================================
 
-uefi-md5sum is a UEFI bootloader designed to perform MD5 checksum verification
-from media containing an `md5sum.txt` list of hashes.
+## Description
+
+uefi-md5sum is a UEFI bootloader designed to perform MD5 hash verification of a
+media containing an `md5sum.txt` list of hashes.
+
+This is primarily aimed at being used with [Rufus](https://rufus.ie) for the
+creation of USB bootable media (such as Linux or Windows installation drives)
+that can perform self-verification on each boot.
+
+The reasoning with wanting to perform validation on boot rather than on media
+creation is based on the fact that flash based media, and especially cheap USB
+flash drives or SD cards, are exceedingly prone to failures **after** the media
+was written.
+
+As such, we assert that, only validating the content at write-time (like
+balenaEtcher and, in part, Microsoft's Media Creation Tool do) is not enough to
+help users ensure that their installation media hasn't become compromised.
+
+This boot time validation can also prove itself useful if the boot process or
+installation process produces errors, in which case, the first thing a user
+may want to do, is reboot and let uefi-md5sum perform its check, to highlight
+or rule out data corruption.
+
+## Usage
+
+uefi-md5sum is intended to replace, and then chain load, the original UEFI
+bootloader.
+
+To accomplish this, the original `/efi/boot/boot###.efi` should be renamed to
+`/efi/boot/boot###_original.efi` with uefi-md5sum bootloader then installed as
+`/efi/boot/boot###.efi`.
+
+## md5sum.txt extensions
+
+If `md5sum.txt` sets an `md5sum_totalbytes` variable, in the form of a comment
+similar to:
+```
+# md5sum_totalbytes = 0x1234abcd
+```
+Then uefi-md5sum interprets this value to be sum of all the file sizes of the
+files referenced in `md5sum.txt`, and uses it for more accurate progress
+reporting. Otherwise, progress is only incremented after each file has been
+processed, regardless of its actual size.
+
+Thus, the provision of `md5sum_totalbytes` allows for accurate progress report,
+as well the avoidance of apparent progress "freezeouts" when very large files
+are being hashed (such as large squashfs or install.wim images).
+
+It should be noted however that, currently, uefi-md5sum supports only the
+provision of an `md5sum_totalbytes` value in **lowercase** hexadecimal (no
+uppercase hex, no decimal). On the other hand, there is no restriction to where,
+in `md5sum.txt`, `md5sum_totalbytes` needs to be specified (i.e. it does not
+necessarily mean to appear at the beginning of the file).
