So you want to try cuttlefish?

1. Download, build, and install the host debian package:

git clone https://github.com/google/android-cuttlefish
cd android-cuttlefish
debuild -i -us -uc -b
sudo dpkg -i ../cuttlefish-common_*_amd64.deb
sudo apt-get install -f

2. Go to http://ci.android.com/
3. Enter a branch name. Start with aosp-master if you don‘t know what you’re looking for
4. Navigate to aosp_cf_x86_phone and click on userdebug for the latest build
5. Click on Artifacts
6. Scroll down to the OTA images. These packages look like aosp_cf_x86_phone-img-xxxxxx.zip -- it will always have img in the name. Download this file
7. Scroll down to cvd-host_package.tar.gz. You should always download a host package from the same build as your images.
8. On your local system, combine the packages:

mkdir cf
cd cf
tar xvf /path/to/cvd-host_package.tar.gz
unzip /path/to/aosp_cf_x86_phone-img-xxxxxx.zip

8. Launch cuttlefish with:

   $ HOME=$PWD ./bin/launch_cvd

9. Stop cuttlefish with:

   $ HOME=$PWD ./bin/stop_cvd

So you want to debug cuttlefish?

You can use adb to debug it, just like a physical device:

$ ./bin/adb -e shell
