Welcome to the moka wiki!
The current site is currently becoming rapidly out of date thus I intend on using this Wiki as a more up to date source of information. Note: the examples in moka-examples repo are also out of date. I will update asap.
Objective-PHP is being worked on at the moment, testing and improving stability. Next I will evaluate any missing language features and then wish to improve performance. Moka is still in its infancy, and will next be getting Key Value Coding and Key Value Observing before improving MKArray and MKString.
For now have a look at the video here
