Where can I get many information about Harmattan, its APIs, and integrating app in the system (Notifications, Search, Events Screen, Sharing, Location, Videos and Music browsers extensions, Calendar, Contacts, Accounts and Instant Messaging) and getting started with them. Before I had very small experience with C++ at all, and a bit of experience with QML, but it has been a long time because now I'm wed developer on Ruby/Rails. But Harmattan really impressed me and I wanna write something useful for it and get N9 Devkit for normal testing my apps and researching Harmattan platform.
For example I even dunno how to enable automatic orientation support for Harmattan app, as well as many basic things.
Please help me. Thanks.
