-= Project "tiniest"
+= Project "Rrq's Tiniest Devuan Excalibur OS"
 
-This project is an experiment of building a tiny linux boot system
-with a single, common syslinux boot configuration used for both legacy
-bios and UEFI bios.
+This project contains a script, `mkit.sh`, that based on Devuan's
+excalibur repository builds a tiny (32 Mb) bootable disk image,
+`bootimage.raw`, with just a Linux kernel and initrd to offer a
+minimal command line shell.
 
-The script +mkit.sh+ prepares such a +bootimage.raw+ and the script
-+vm.sh+ runs a Qemu VM for testing it.
+That "**Rrq's Tiniest Devuan Excalibur OS**" is intended to be a start
+point for someone with technical interest in the very first boot
+stages, as well as for someone who wish to set up their own OS/Desktop
+distribution without carrying much or any excess software.
 
-In addition, the script +packit.sh+ runs xorriso to prepare an ISO
-with that boot image, to boot either as cdrom for legacy bios or with
-EFI partition with for UEFI bios.
+The way to get it tiny is of course to rely on busybox-static which is
+a single binary that caters for a large range of "standard" commands
+depending on which (command) name it is invoked as. Other than using
+that, it is then a matter of only including the most important kernel
+modules.

+This project also contains a few other scripts, in particular `vm.sh`
+for running a Qemu virtual machine to trial either `bootimage.raw` in
+its alternative bios use cases, and `packiso.sh` which prepares a
+bootable hybrid ISO with `bootimage.raw` and more.
 
-* Kernel version +$VERSION+ is obtained from the linux-image-amd64
-  dependency.
+The interested developer/explorer would start by investigating, and
+probably tuning, the steps of the `mkit.sh` script so as to compose
+their own special disk image. As is, the script prepared a disk image
+that includes boot equipments both for legacy bios boot and for UEFI
+bios boot. Both of the boot equipments are deployments of syslinux
+boot software that arekept together in the first disk image partition
+with an EFI/FAT file system. The disk image also has a empty `ext4`
+partition that may be extended to becomve a larger, second stage root
+file system.
