Looking for documentation on input methods

[jimhabegger]

More specifically, I'm currently looking for guides for the Zhengma input method, in any language, that I can download for free. I've found a tutorial by Megatron Cookie to buy or to read on line, but I can't find anything to download for free.

I'm also trying to learn Wubi. I've found a good tutorial for that, by Joe Wicentowski, but I'd be glad to know about any others. I'd also like to find documentation on other input methods included with Microsoft Windows: QuanPin and ShuangPin.
