The B2G OS platform

Documentation about the B2G OS platform

The B2G OS platform consists of many components. While you don't need to understand its architecture in order to build applications that run on B2G OS, if you're working on developing or porting the platform — or are simply curious — the following documentation may be of interest to you.

B2G OS architecture overview
An overview of how B2G OS is structured internally; this is primarily of interest to platform developers and people doing porting work.
B2G OS apps architecture
An overview of the application model on B2G OS.
Documentation about Gaia, the user interface application for B2G OS devices; this is a Web application running atop the B2G OS software stack.

Gecko is the layer of B2G OS that provides the same open web standards implementation used by Firefox and Thunderbird, as well as many other applications.
Documentation about security in B2G OS; this includes topics about security devices from every perspective: for app developers, device integrators, and so forth.
