can't build the docker image with error saying image not found

[helxsz]

am trying to build a docker image from public repository - https://github.com/dockerfile/ghost. Actually I had built it successfully before, toady I wanted to update the image to latest one, so I removed the older image, and tried to pull the new image.

However, when I tried

$ docker pull dockerfile/ghost
Pulling repository dockerfile/ghost
FATA[0001] Error: image dockerfile/ghost:latest not found

I can't really understand why it doesn't work, it is supposed to be working.

I was surprised https://registry.hub.docker.com/_/ghost/
ghost now is official repo of docker!

So @pilwon please fix README.md file.
