+
+Boot to Gecko aims to create a complete, standalone operating system for the open web.
+
+You can read more about B2G here:

+
+## Prerequisites
+
+### Linux
+
+* A 64 bit linux distro
+  * See http://source.android.com/source/initializing.html on configuring USB access.
+* 20GB of free disk space
+* autoconf-2.13
+* git
+* ccache
+* gcc/g++
+* bison
+* 32bit ncurses
+* make
+
+### OSX
+
+* XCode
+* 20GB of free space on a case sensitive filesystem
+  * See http://source.android.com/source/initializing.html on creating a case sensitive disk image.
+* homebrew
+  * git
+  * gpg
+  * ccache
+  * autoconf-2.13 - brew install https://raw.github.com/Homebrew/homebrew-versions/master/autoconf213.rb
+
+## Configuration
+
+Run config.sh to get a list of supported devices:
+
+    ./config.sh
+
+And then run config.sh for the device you want to build for:
+
+    ./config.sh [device name]
+
+## Build
+
+Run build.sh or bld.sh to build B2G.
+
+    ./build.sh
+
+If you want to just build gecko or some other project, just specify it:
+
+    ./build.sh gecko
+
+## Flash/Install
+
+Make sure your phone is plugged in with usb debugging enabled.
+
+To flash everything on your phone:
+
+    ./flash.sh
+
+To flash system/userdata/boot partitions on fastboot phones:
+
+    ./flash.sh system
+    ./flash.sh boot
+    ./flash.sh user
+
+To update gecko:
+
+    ./flash.sh gecko
+
+To update gaia:
+
+    ./flash.sh gaia
+
+## Debug
+
+To restart B2G and run B2G under gdb:
+
+    ./run-gdb.sh
+
+To attach gdb to a running B2G process:
+
+    ./run-gdb.sh attach
