 Prerequisites
 -------------
 
 _Currently we only support building Skia for Android on a Linux or Mac host! In addition,
  we only use the Mac build for local development. All shipping variants are compiled on
  Linux for performance reasons._
 
 The following libraries/utilities are required in addition to those needed for a standard skia checkout:
 
   * The Android SDK: http://developer.android.com/sdk/
 
 Check out the source code
 -------------------------
 
 Follow the instructions [here](../download) for downloading the Skia source. 
 
 Inside your Skia checkout, `platform_tools/android` contains the Android setup
 scripts, Android specific dependencies, and the Android Sample App.
 
+You may need to [install other dependencies](./linux#prerequisites):

I think what you want is:

<pre class="prettyprint bsh">
tools/install_dependencies.sh
</pre>

 Setup the Android SDK
 ---------------------
 
 To finish setting up the Android SDK you need to download use the SDK to
 download the appropriate API level.  To do this simply go to the directory
 where you installed the SDK and run the following commands
 
     # You may want to add this export to your shell's .bash_profile or .profile
     export ANDROID_SDK_ROOT=/path/to/android/sdk

     # SAMPLE APP
     # make sure you've installed the app on the device first

 When the gdb client is ready, insert a breakpoint, and continue to let the
