Yeah... right now, code contributions for Qcodo.com are a bit tougher to handle.
I'll try and do a wiki write up for it when I get a spare moment... but in the meantime, if you're a bit more daring =) you can feel free to get the code from GitHub, or better yet, set up an account on github for yourself and then post a public branch.
The code, itself, is just on qcodo 0.4.3 so if you're familiar enough with qcodo, it should be pretty straightforward to set up. just be sure to update configuration.inc.php to whatever your dev settings happen to be.
In the database directory, there is a make.sh shell script which will make your qcodo.com database for you -- just be sure to update make.sh to, again, whatever your local dev environment settings happen to be.
And finally, if everything is running properly, you should be able to run cli/qcodo data-loader to have Qcodo randomly generate a bunch of data for you into your local dev qcodo.com database so that you can actually run a website in your local dev environment with real-ish looking data. =)
