-# Prerequisites
-  * a Linux/Mac workstation
-  * v8 r12178 (on Google Code) or later
-  * an Android emulator or device with matching USB cable
-  * make sure [building with GYP](http://code.google.com/p/v8-wiki/wiki/BuildingWithGYP) works
-
-
-# Get the code
-
-  * Use the instructions from https://code.google.com/p/v8-wiki/wiki/UsingGit to get the code
-  * Once you need to add the android dependencies:
-```
-v8$ echo "target_os = ['android']" >> ../.gclient && gclient sync --nohooks
-```
-  * The sync will take a while the first time as it downloads the Android NDK to v8/third\_party
-  * If you want to use a different NDK, you need to set the gyp variable android\_ndk\_root
-
-
-# Get the Android SDK
-  * tested version: `r15`
-  * download the SDK from http://developer.android.com/sdk/index.html
-  * extract it
-  * install the "Platform tools" using the SDK manager that you can start by running `tools/android`
-  * now you have a `platform_tools/adb` binary which will be used later; put it in your `PATH` or remember where it is
-
-
-# Set up your device
-  * Enable USB debugging (Gingerbread: Settings > Applications > Development > USB debugging; Ice Cream Sandwich: Settings > Developer Options > USB debugging)
-  * connect your device to your workstation
-  * make sure `adb devices` shows it; you may have to edit `udev` rules to give yourself proper permissions
-  * run `adb shell` to get an ssh-like shell on the device. In that shell, do:
-```
-cd /data/local/tmp
-mkdir v8
-cd v8
-```
-
-
-# Push stuff onto the device
-  * make sure your device is connected
-  * from your workstation's shell:
-```
-adb push /file/you/want/to/push /data/local/tmp/v8/
-```
-
-
-# Compile V8 for Android
-Currently two architectures (`android_arm` and `android_ia32`) are supported, each in `debug` or `release` mode. The following steps work equally well for both ARM and ia32, on either the emulator or real devices.
-  * compile:
-```
-make android_arm.release -j16
-```
-  * push the resulting binary to the device:
-```
-adb push out/android_arm.release/d8 /data/local/tmp/v8/d8
-```
-  * the most comfortable way to run it is from your workstation's shell as a one-off command (rather than starting an interactive shell session on the device), that way you can use pipes or whatever to process the output as necessary:
-```
-adb shell /data/local/tmp/v8/d8 <parameters>
-```
-  * warning: when you cancel such an "adb shell whatever" command using Ctrl+C, the process on the phone will sometimes keep running.
-  * Alternatively, use the `.check` suffix to automatically push test binaries and test cases onto the device and run them.
-```
-make android_arm.release.check
-```
-
-
-# Profile
-  * compile a binary, push it to the device, keep a copy of it on the host
-```
-make android_arm.release -j16
-adb push out/android_arm.release/d8 /data/local/tmp/v8/d8-version.under.test
-cp out/android_arm.release/d8 ./d8-version.under.test
-```
-  * get a profiling log and copy it to the host:
-```
-adb shell /data/local/tmp/v8/d8-version.under.test benchmark.js --prof
-adb pull /data/local/tmp/v8/v8.log ./
-```
-  * open `v8.log` in your favorite editor and edit the first line to match the full path of the `d8-version.under.test` binary on your workstation (instead of the `/data/local/tmp/v8/` path it had on the device)
-  * run the tick processor with the host's `d8` and an appropriate `nm` binary:
-```
-cp out/ia32.release/d8 ./d8  # only required once
-tools/linux-tick-processor --nm=$ANDROID_NDK_ROOT/toolchain/bin/arm-linux-androideabi-nm
-```
-
-# Compile SpiderMonkey for Lollipop
-```
-cd firefox/js/src
-autoconf2.13
-./configure \
-  --target=arm-linux-androideabi \
-  --with-android-ndk=$ANDROID_NDK_ROOT \
-  --with-android-version=21 \
-  --without-intl-api \
-  --disable-tests \
-  --enable-android-libstdcxx \
-  --enable-pie
-make
-adb push -p js/src/shell/js /data/local/tmp/js
-```
