I was very keen to try out Google Coder for the Raspberry Pi as soon as I heard about it. I had some problems with it initially because the instructions on the Google Coder download site are/were fairly scant.
It talks of an installer, which it later transpires is only for the Mac. The instructions have since improved a bit, but initially were hopelessly confusing.
I hope the instructions will have improved even more by the time you read this, but below I’ll show you how I got it up and running.
These are instructions for a PC running Windows (7). For Mac, you can allegedly run the installer. For Linux, I expect a similar procedure will work.
Download the file
Go and download the file. It’s ~ 1 Gb and is a full system image.
Unzip your file
You will end up with a folder called coder_v0.4 although with time, that version number will change. Inside that folder, there’s another folder called coder_v0.4 and under that, is an SD card image file called raspi.img
Find Your disk image file
So its location will be…
wherever you unzipped the file to.../coder_v0.4/coder_v0.4/raspi.img
Flash an SD card
Flash the above .img file to an SD card (>= 4 Gb).

Your first boot is as a normal Raspbian boot, with screen, keyboard, ethernet. You will need to go through the normal choices screen to fully finish setting up the OS (e.g. extending the partition, etc.)
Once you reboot, your Pi should be ready to use with Google Coder.
Now Bonjour to your Windows PC
For Google Coder to work, Windows users need to install Apple’s Bonjour print services, which can be found here…
Once that’s installed, you should be good to go, as long as you have Chrome or Internet Explorer.
Ensure your Pi is up and running (having been through the “first boot” process).
From your PC, open Chrome or Internet Explorer and navigate to the URL…
You may have to click “proceed anyway” because it uses https and your Pi will not have a trusted certificate.
The first time it will get you to choose a password, but it imposes its own security rules, so “raspberry” won’t work.
Once you’ve chosen a password, it will ask you to login and then you should be good to go.
What does it do?
Other than that it works as shown in their promotional video.
Coder is a free, open source project that turns a Raspberry Pi into a simple platform that educators and parents can use to teach the basics of building for the web.
I’m sure that they will improve their instructions soon, but for now, I hope this helps.
In the meantime, I’m off for a game of the Asteroids clone (called Space Rocks) they included with it…
If you want to shut down cleanly you can ssh into the Pi using the pi userid and the password you chose for Google Coder.

Phil “Gadgetoid” Howard has just posted some instructions for how to install Google Coder without reimaging your SD card.
