Please review, since my english is not the best. Thanks.
(Otherwise I will merge in about one week)

+*** Transfer ISO image to target medium (configs/releng)
+
+ISO images names consist of: archlinux-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+
+Where:
+ <YYYY> Year
+ <MM> Month
+ <DD> Day
+ <TYPE> netinstall | core
+ <ARCH> i686 | x86_64 | dual(*)
+
+(*) "dual" includes both i686 and x86_64 architectures.
+
+
+** To -> CD / DVD / BD
+Note: All ISO images are booteable on a PC-BIOS via "El Torito" in no-emulation mode,
+ All x86_64 ISO images are booteable on a PC-EFI via "El Torito" in no-emulation mode.
+
+Nomeclature:
+ <B> scsibus number
+ <T> target number
+ <L> lun number
+ (Note: see cdrecord -scanbus, for these numbers)
+
+
+1) Write it directly using your favorite recording program.
+# cdrecord dev=<B>,<T>,<L> -dao archlinux-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+
+
+** To -> USB Flash Drive (USB-key) / Memory card (SD) /
+ Hard-Disk Drive (HDD) / Solid-State Drive (SSD)
+
+Note: These steps are the general workflow, you can skip some of them,
+ using another filesystem if your bootloader supports it,
+ or installing to another directory than "arch/".
+ Just ensure that main boot params options (archisolabel= and
+ archisobasedir=) are set correctly according to your setup.
+
+Nomeclature:
+<DEV-TARGET>: Device node of the drive where ISO contents should be copied
+ (example: /dev/sdx)
+<DEV-TARGET-N>: Device node of the partition on <DEV-TARGET>
+ (example: /dev/sdx1)
+<MNT-TARGET-N>: Mount point path where <DEV-TARGET-N> is mounted
+ (example: /mnt/sdx/1)
+<ISO-SOURCE>: Path to the ISO file archlinux-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+ (example: ~/archlinux-2012.04.16-netinstall-x86_64.iso)
+<FS-LABEL>: Represents the filesystem label of the <ISO-SOURCE>
+ (example: ARCH_201204 [for all ~/archlinux-2012.04.*.iso])
+
+
+* PC-BIOS (MBR):
+
+1) Create one partition entry in MBR (of type "b" for FAT32 or "83" for EXTFS)
+ and mark it as "active" (booteable).
+# fdisk <DEV-TARGET>
+
+2) Create a FAT32 or EXTFS filesystem on such partition and setup a label.
+# mkfs.vfat -F 32 -n <FS-LABEL> <DEV-TARGET-N>
+# mkfs.ext2 -L <FS-LABEL> <DEV-TARGET-N>
+
+3) Mount target filesystem.
+# mount <DEV-TARGET-N> <MNT-TARGET-N>
+
+4) Extract ISO image on target filesystem.
+# bsdtar -x --exclude=isolinux/ --exclude=EFI/ -f <ISO-SOURCE> -C <MNT-TARGET-N>
+
+5) Install syslinux bootloader on target filesystem.
+# extlinux -i <MNT-TARGET-N>/arch/boot/syslinux
+
+6) Unmount target filesystem.
+# umount <MNT-TARGET-N>
+
+7) Install syslinux MBR boot code on target drive.
+# dd bs=440 count=1 conv=notrunc if=/usr/lib/syslinux/mbr.bin of=<DEV-TARGET>
+
+
+* PC-BIOS (ISOHYBRID-MBR):
+
+This method is the most easily, quick and dirty,
+but is the most limited if you want to use your target medium for other purposes.
+
+1) Dump ISO file to target medium.
+# dd if=<ISO-SOURCE> of=<DEV-TARGET>
+
+
+* PC-EFI (GPT) [x86_64 only]
+
+Note: Using here a GPT partition mode, but MBR should also work.
+ Optionally you can use your favorite EFI boot manager instead of an efi-shell+startup.nsh.
+
+1) Create one partition entry in GPT (of type "ef00")
+# gdisk <DEV-TARGET>
+
+2) Create a FAT32 filesystem on such partition and setup a label.
+# mkfs.vfat -F 32 -n <FS-LABEL> <DEV-TARGET-N>
+
+3) Mount target filesystem.
+# mount <DEV-TARGET-N> <MNT-TARGET-N>
+
+4) Extract ISO image on target filesystem.
+# bsdtar -x --exclude=isolinux/ --exclude=arch/boot/syslinux/ -f <ISO-SOURCE> -C <MNT-TARGET-N>
+
+5) Extract efiboot.img on EFI/ on target filesystem.
+# mcopy -s -i <MNT-TARGET-N>/EFI/archiso/efiboot.img ::/EFI <MNT-TARGET-N>/
+
+6) Remove uneeded efiboot.img
+# rm <MNT-TARGET-N>/EFI/archiso/efiboot.img
+
+7) Unmount target filesystem.
+# umount <MNT-TARGET-N>
+
+
