+# Alpine Linux netboot
+
+Welcome to the Alpine Linux netboot server.
+
+Netboot provides kernel initramfs and modloop images to boot over the
+network/internet. Booting from netboot is provided by the IPXE binaries
+available in alpine-ipxe `apk add alpine-ipxe` or from
+[this location](alpine-ipxe).
+
+## Boot script
+
+The default bootscript for alpine-ipxe is
+**[https://boot.alpinelinux.org/boot.ipxe](boot.ipxe)** which will automatically
+be fetched by alpine-ipxe. If you like to change this behaviour you will need to
+build your own version of [ipxe](https://ipxe.org).
+
+Some cloud providers (ie [packet.net](https://help.packet.net/technical/infrastructure/custom-ipxe))
+support the loading of custom ipxe scripts/payloads to install an operating
+system. You can chainload one of the ipxe loaders from [alpine-ipxe](alpine-ipxe).
+Don't load the boot.ipxe script directly as image verifications will fail.
+
+## Images
+
+Images are hosted in the [Images](images) directory on boot.alpinelinux.org.
+Current available images are:
+
+* **edge**
+  * [x86](images/edge/x86)
+  * [x86_64](images/edge/x86_64)
+* **latest-stable**
+  * [x86](images/latest-stable/x86)
+  * [x86_64](images/latest-stable/x86_64)
+
+## Signed images
+
+Alpine Linux images are signed and can be verified only by making use of
+[alpine-ipxe](alpine-ipxe). Using another ipxe loader will not trust our 
+signatures and will result in failed boot.
+
+## Boot options
+
+### BIOS
+
+* [pxe.lkrn](alpine-ipxe/ipxe.lkrn) - Linux kernel image that can be used by a bootloader/qemu
+* [pxe.pxe](alpine-ipxe/ipxe.pxe) - PXE image for chainloading from a PXE environment
+* [undionly.kpxe](alpine-ipxe/undionly.kpxe) - PXE image with UNDI support
+* [ipxe.iso](alpine-ipxe/ipxe.iso) - ISO image to boot from any regular system
+
+### UEFI
+
+* [ipxe.efi](alpine-ipxe/ipxe.efi) x86_64 UEFI executable
+
+## Updates
+
+Netboot images are updated every night automatically if any package in the
+dependecy tree (kernel and alpine-base) has been updated. Regular packages are
+updated automatically via our package repositories.
+
+## Testing netboot
+
+The easiest way to test is by using Qemu directly with the ipxe kernel image.
+
+`apk add qemu-system-x86_64 alpine-ipxe`
+
+`qemu-system-x86_64 -m 512M -enable-kvm -kernel /usr/share/alpine-ipxe/ipxe.lkrn -curses`
+
+**NOTE**: you need a minimum of 256M of memory to boot alpine in network mode
+due to the size of our initramfs and modloop (kernel modules).
