Hello!

What about to add some Zephyr wiki? There are lot of ready wiki engines exists. 

Why need it? I believe Zephyr has a serious lack of documentation. Mostly about how to do some things, code examples, configuration,  use cases etc. etc.   

I just almost resolved my issues with I2C setup so has an information to share - how to do it, what to check and where to look for it. 
But have no place for it. Of course I wil put it to my own blog - but I think some shared place for documentation where each can contribute could be useful. 

Why not post it here? 

Here in grous where a tons of questions so mostly it is a trash (in a wide meaning).  Any howto or an articles will be lost among it.
