+## Docker Hub
+
+There are images on Docker Hub to help with reproducible builds. These are built (by hand) from `alpine/base`,
+generally with tags based on the image contents.
+
+- `mobylinux/alpine-base` the base packages for Moby, before we add Docker and our code and config
+- `mobylinux/alpine-build-c` for building C code
+- `mobylinux/alpine-build-go` for building Go code
+- `mobylinux/alpine-bios` for building BIOS image
+- `mobylinux/alpine-efi` for building efi images
+- `mobylinux/alpine-qemu` for Qemu eg for the tests
+- `mobylinux/debian-build-kernel` for the kernel builds while we cannot use Alpine
+
+In addition
+- `mobylinux/media` contains build artifacts
+
+You can upload build artifacts with `make media` or `make media MEDIA_PREFIX=1.12.0-` if you want to change the prefix of the git hash.
+The will by default be prefixed by `experimental-` if they are Docker experimental builds. These are used in the Mac and Windows build
+process to get the images.
+
+Ping @justincormack if you need access to the Hub organization.
