Some days back I wrote about a WIP of The Book on Aura
It got some attention and pull requests.
Akihito Koriyama have already started to convert the documentation to Japanese.
And today I am happy to announce that it is officially going to the manuals.
Fork https://github.com/auraphp/auraphp.github.com and contribute to the manuals.
The manuals are in different languages. Currently
Akihito Koriyama is working on Japanese translation.
We are aware some parts of the manual needs a rewrite / more explanation. If you are interested to learn and contribute get in touch via http://groups.google.com/group/auraphp.
