 ## Recipe2: Explicit Cross compiling
 
 Due to the lack of ARM hardware with the grunt to build Chromium native, cross
 compiling is currently the recommended method of building for ARM.
 
 These instruction are designed to run on Ubuntu Precise.
 
 ### Installing the toolchain
 
 The install-build-deps script can be used to install all the compiler
 and library dependencies directly from Ubuntu:
 
     $ ./build/install-build-deps.sh
 
 ### Installing the sysroot

+A prebuilt sysroot image is kept up to date on Cloud Storage. It will
 automatically be installed by gclient runhooks installed if you have
 `target_arch=arm` in your `GYP_DEFINES`.
 
 To install the sysroot manually you can run:
 
     ./chrome/installer/linux/sysroot_scripts/install-debian.wheezy.sysroot.py \
         --arch=arm

 ### Notes
 
 *   To building for thumb reduces the stripped release binary by around 9MB,
     equating to ~33% of the binary size.  To enable thumb, set `'arm_thumb': 1`
 *   TCmalloc does not have an ARM port, so it is disabled.
