Really "opening" this project means to have a license

Problem

The source code and tutorial are both available online, but the default copyright in most countries forbid people from using it legally

Solution

Add a license to the repository and all it's files and other people can use it legally.

Because it is not really source code it shouldn't be a program license like GPL.

My advice:

• CC-BY-SA - this is used by many many human language projects like Wikipedia (!)
• GFDL - the internet says it should also be good, but I've read that the CC-BY-SA is used much more often

If you want help in implementing one or another, tell me. I'm happy to help!

GFDL has issues with respect to the Debian Free Software Guidelines. One of the free CC licenses, such as by-sa as you suggest, is a really good choice IMHO.

@merwok see #7. I completely agree. That's also why I always choose CC when possible.
