Sorry to be dense, but how is the container built?

I was happy to learn that `image/Readme.md` says

```plaintext
To build a new set of images, update the `Makefile` with the new version number, and then `make all`. 

```

Sounds simple. Sadly, there is no Makefile to be found.

Then I thought that I could just build with

```
cd images; docker build discourse_dev

```

(And I tried running that from some other directories..) but that fails with

```plaintext
Step 6/17 : ADD redis.template.yml /pups/redis.yml
ADD failed: stat /var/lib/docker/tmp/docker-builder410839948/redis.template.yml: no such file or directory

```

I’m running out of ideas.
