+Running Wrench on Android devices.
+==================================
+
+Setting up the environment:
+---------------------------
+
+Follow the steps at https://github.com/rust-windowing/android-rs-glue#setting-up-your-environment, with exceptions:
+    - No need to download the Android NDK and SDK, we will use the ones downloaded by Gecko in ~/.mozbuild/
+
+    - Install both the i686-linux-android and armv7-linux-androideabi rust
+      targets, as the APK will include native libraries with both architectures.
+
+    - Don't install currently published version of cargo-apk, as it is missing the following
+      required patch: https://github.com/rust-windowing/android-ndk-rs/pull/236
+
+      Instead, install the git master version like so:
+        cargo install --git https://github.com/rust-windowing/android-ndk-rs cargo-apk
+
+    - Consider adding ~/.mozbuild/android-sdk-linux/platform-tools to your path, for the adb commands below.
+
+Compiling and running:
+----------------------
+
+    Compile wrench:
+        cd wrench
+        export ANDROID_SDK_ROOT=$HOME/.mozbuild/android-sdk-linux # exact path may vary
+        export ANDROID_NDK_ROOT=$HOME/.mozbuild/android-ndk-r21d  # exact path may vary
+        cargo apk build --lib
+
+    Install the APK:
+        adb install -r ../target/debug/apk/wrench.apk
+
+    Set command line arguments and env vars for wrench:
+        adb shell
+        mkdir /data/data/org.mozilla.wrench/files/wrench
+        echo "load reftests/aa/rounded-rects.yaml" >/data/data/org.mozilla.wrench/files/wrench/args
+        echo "env: WRENCH_REFTEST_CONDITION_EMULATOR=1" >>/data/data/org.mozilla.wrench/files/wrench/args # If you're using the emulator
+        echo "env: WRENCH_REFTEST_CONDITION_DEVICE=1" >>/data/data/org.mozilla.wrench/files/wrench/args # If you're using a device
+        exit
+
+    Push reftests (if you need these files for what you're doing):
+        adb push reftests /data/data/org.mozilla.wrench/files/wrench/
+
+    Run the application:
+        adb shell am start -n org.mozilla.wrench/android.app.NativeActivity
+            (or click the icon in the launcher)
+
+    Inspect the output:
+        stdout and stderr will be redirected to the logcat, however, long lines will be truncated
+        meaning the reftest analyzer will not work correctly. We therefore additionally redirect the
+        output to the file /data/data/org.mozilla.wrench/files/wrench/stdout.
+
+Release mode:
+-------------
+
+    Building in release does work as well. Use the following steps to compile wrench:
+        cd wrench
+        export ANDROID_SDK_ROOT=$HOME/.mozbuild/android-sdk-linux # exact path may vary
+        export ANDROID_NDK_ROOT=$HOME/.mozbuild/android-ndk-r21d  # exact path may vary
+        cargo apk build --lib --release
+
+    Now the APK at ../target/release/apk/wrench.apk
+    should be signed and installable (you may need to uninstall the debug APK first if you
+    have that installed).
+
+Running reftests like a boss (on a local emulator):
+---------------------------------------------------
+
+    First, compile wrench as described above (debug mode).
+    Then, from the root gecko source dir, run:
+        ./mach python testing/mozharness/scripts/android_wrench.py --config testing/mozharness/configs/android/wrench.py
+    This will automatically do the following:
+        - Download the blessed android AVDs from taskcluster
+        - Start the emulator (using your ~/.mozbuild/android-sdk-linux emulator binaries)
+        - Install the debug APK (from gfx/wr/wrench/target/debug/apk/wrench.apk)
+        - Copy the reftests to the sdcard
+        - Write an args file to the sdcard
+        - Run wrench
+        - Wait for wrench to finish running
+        - Scrape the logcat for reftest output
+    Other logs (e.g. full logcat) can be found in your ~/.wrench/logs folder. Note that
+    this will also leave the android emulator running, so repeating the command will be
+    even faster the next time around as it won't need to redownload the AVDs or restart
+    the emulator. It will reinstall the APK and re-push the reftests folder though.
+
+    If you want to use a release APK (runs much faster), build it as per the "Release mode"
+    instructions above and set the WRENCH_APK env var to point to the APK:
+    to point to it:
+        export WRENCH_APK=gfx/wr/target/release/apk/wrench.apk
+        ./mach python testing/mozharness/scripts/android_wrench.py --config testing/mozharness/configs/android/wrench.py
+
+Running reftests like a boss (on a local device):
+-------------------------------------------------
+
+    Same steps as running on a local emulator, except you need to do this:
+        export DEVICE_SERIAL=<your device's serial>
+    before running the `./mach python` command. You can get the serial of
+    your device by running `adb devices` with the device plugged in. When running
+    on a device, the android_emulator_wrench.py script will skip the steps to
+    download the AVDs and start the emulator.
