-Overview
-========
-
-Devsus is a script that builds bootable, libre Devuan (http://www.devuan.org/)
-images for the Asus C201 Chromebook, one of the few laptops able to boot and run
-without any non-free software, all the way down to the firmware level. The C201
-is supported by Libreboot (http://www.libreboot.org/).
-
-The images produced by Devsus contain a Linux-libre
-(http://linux-libre.fsfla.org/) longterm kernel tuned for small size, good
-performance and short boot times.
-
-Some features of the RK3288 SoC, including built-in WiFi support, require use of
-non-free software. Therefore, they are unsupported by Devsus. To compensate for
-that, the Devsus kernel includes support for freedom-friendly devices:
-
-	- Firmware for Atheros AR9271 based WiFi dongles
-	- Drivers for Qualcomm CSR8510 based Bluetooth dongles
-
-Moreover, the Devuan installation is very minimal and consists of a barebones
-Devuan base, plus crucial command-line tools, like those required to connect to
-a WiFi network.
-
-Dependencies
-============
-
-Devsus has been tested on Devuan 2 (ASCII) on x86_64, with the following
-packages installed:
-
-	apt install --no-install-recommends --no-install-suggests \
-		parted cgpt \
-		git gawk device-tree-compiler vboot-kernel-utils gcc-arm-none-eabi \
-			u-boot-tools \
-		gcc make libc-dev wget g++ cmake \
-		binfmt-support qemu-user-static debootstrap \
-		bc wget xz-utils m4
-
-Building
-========
-
-	# ./devsus.sh
-
-This produces two Devuan disk images:
-
-	1) devuan-ascii-c201-libre-16GB.img, a 16 GB image suitable for persistent
-	   installation; its size should be exactly the size of the internal SSD
-	2) devuan-ascii-c201-libre-2GB.img, a 2 GB image suitable for booting the
-	   laptop off USB
-
-Usage
-=====
-
-To produce a bootable media, write the 2 GB image to a flash drive (of at least
-2 GB):
-
-	# dd if=$SOMEWHERE/devuan-ascii-c201-libre-2GB.img of=/dev/$DEVICE bs=50M
-
-The root password is blank.
-
-The 2 GB image (yes, the smaller one) contains the larger, 16 GB one under /.
-This way, it is possible to boot the laptop through USB, then install Devuan
-persistently without having to download or store the large image separately.
-
-Persistent installation is performed using dd, too:
-
-	# dd if=/devuan-ascii-c201-libre-16GB.img of=/dev/mmcblk0
-
-Modifications
-=============
-
-The images produced by Devsus are very close to stock Devuan:
-
-	- APT has been configured not to install "recommended" packages by default
-	- Some critical (like udev) or useful (like iw) packages have been added
-	- unscd has been added, to cache DNS
-	- The number of virtual consoles has been reduced from 6 to 2
-
-Credits and Legal Information
-=============================
-
-Devsus' previous kernel building procedure was based on the linux-veyron package
-of Arch Linux ARM (http://www.archlinuxarm.org/).
-
-Devsus' workaround for ath9k_htc instability issues has been adopted from
-PrawnOS (https://github.com/SolidHal/PrawnOS) and found by SolidHal.
