+# So you want to try cuttlefish?
+
+1. Go to http://ci.android.com/
+2. Enter a branch name. Start with `aosp-master` if you don't know what you're
+   looking for
+3. Navigate to `aosp_cf_x86_phone` and click on `userdebug` for the latest build
+4. Click on `Artifacts`
+5. 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
+6. Scroll down to `cvd-host_package.tar.gz`. You should always download a host
+   package from the same build as your images.
+7. 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`
+
+# So you want to see cuttlefish?
+
+You can use the [TightVNC JViewer](https://www.tightvnc.com/download.php). Once
+you have downloaded the *TightVNC Java Viewer JAR in a ZIP archive*, run it with
+
+   `$ java -jar tightvnc-jviewer.jar -ScalingFactor=50 -Tunneling=no -host=localhost -port=6444`
+
+Click "Connect" and you should see a lock screen!
