I'm so glad your repurposing Fido! I was so happy to see that putting some parts of my tutorial in wiki pages allowed you to integrate them easily into your tutorial. If you see any explanations worth improving, please get in there an edit away.
It looks like this was freshly edited but I just wanted to say that it looks like the code specific to your application is missing. Trying to use GitHub can be difficult at first but its well worth it since it makes it easier for other people to contribute. I would have no problem looking at your code and maybe adding that extra functionality that you mention if I could easily access it on GitHub. I am actually wondering how big your sketch is so far because that was the limitation with Fido (I ran out of space!).
Anyway, let me know if I can help at all. Great build!
