Hello World: An introduction to open source
Hello World is an introductory booklet to open source. It looks at what open source is, why it's great and how you can get involved. It's available in a limited run print edition from the CSM Pop up shop 2012.
So why is it on Github? Well the whole booklet is available here, so that you can create your own version, add to it, or simply just use any of the assets in your own work.
