+Rock64 Arch Linux Image Builder
+===============================
+
+Overview
+--------
+This code will build a pretty "vanilla" Arch Linux ARM image for the Rock64 Single Board Computer.
+
+It builds u-boot using ayufan's scripts (from https://github.com/ayufan-rock64/linux-build/, https://github.com/ayufan-rock64/linux-u-boot/). Then, it use guestfish to create an empty image, partition it as required by the RK3328, format the `boot` and `linux-root` partitions, and extract the [Arch Linux ARM ARMv8 generic](https://archlinuxarm.org/platforms/armv8/generic) tarball into the image. It will then add the u-boot bootloader, extlinux config with the kernel command line args and fix the serial console.
+
+Build procedure
+---------------
+This is written from the perspective of someone building the image on Arch Linux x86_64.
+
+Install the following prerequisites (mostly required for building u-boot):
+* `aarch64-linux-gnu-gcc`
+* `guestfish`
+* `dtc`
+* `git`
+* `uboot-tools`
+* `swig`
+* `make`
+
+Then:
+```
+make [arch.img]
+```
+
+Usage
+-----
+Burn image to sdcard or eMMC. Boot.
+
+username/password: `alarm`/`alarm`
+`root` password: `root`
+
+When using SSH, login as `alarm` first, then `su root`.
+
+Known/potential issues
+------------
+* If you suffer from network performance issues, [try disabling rx and tx pauses using ethtool](https://github.com/ayufan-rock64/linux-build/blob/master/package/root/etc/network/if-up.d/rock64-offload)
+
+Things to do
+------------
+In no particular order:
+
+- [ ] Figure out how to install extra packages (currently, guestfish's `command` running ability cannot be used because of the mismatch in architectures in the guest image and host)
+- [ ] Create systemd unit file for the ethtool setup (see above)
+- [ ] Contribute Arch Linux support back into ayufan's [linux-build](https://github.com/ayufan-rock64/linux-build/) repo, assuming it's desired.
+- [ ] Build Arch Linux packages for ayufan's kernels.
+
+Credits
+-------
+* ayufan for his excellent work on building Rock64 images. Many parts of this repo are inspired by his [linux-build](https://github.com/ayufan-rock64/linux-build/) and other code. The following are (almost) directly taken from his code:
+  * `extlinux.conf`
+  * `Makefile.*.mk`
+* Rockchip for caring about mainline support for their chips
+* Arch Linux ARM for the distribution
+* [Arch Linux Wiki page on banana pi](https://wiki.archlinux.org/index.php/Banana_Pi) for a pointer on fixing python library loading issues when building u-boot
