+# VmAttestationDemoApp
+
+## Overview
+
+The *VmAttestationDemoApp* is an Android application that provides a practical
+demonstration of how to interact with the VM Attestation APIs. This app focuses
+on the payload of the Android app and the payload performs two main tasks:
+requesting attestation and validating the attestation result.
+
+## Building
+
+To build the VmAttestationDemoApp, use the following command:
+
+```
+m VmAttestationDemoApp
+```
+
+## Installing
+
+To install the app on your device, execute the following command:
+
+```
+adb install $ANDROID_PRODUCT_OUT/system/app/VmAttestationDemoApp/VmAttestationDemoApp.apk
+```
+
+## Running
+
+Before running the app, make sure that the device has an internet connection and
+that the remote provisioning host is not empty. You can use the following
+command to check the remote provisioning host:
+
+```
+$ adb shell getprop remote_provisioning.hostname
+remoteprovisioning.googleapis.com
+```
+
+Once you have confirmed the remote provisioning host, you can run the app using
+the following command:
+
+```
+TEST_ROOT=/data/local/tmp/virt && adb shell /apex/com.android.virt/bin/vm run-app \
+  --config-path assets/config.json --debug full \
+  $(adb shell pm path com.android.virt.vm_attestation.demo | cut -c 9-) \
+  $TEST_ROOT/VmAttestationDemoApp.apk.idsig \
+  $TEST_ROOT/instance.vm_attestation.debug.img --protected
+```
+
+Please note that remote attestation is only available for protected VMs.
+Therefore, ensure that the VM is launched in protected mode using the
+`--protected` flag.
+
+If everything is set up correctly, you should be able to see the attestation
+result printed out in the VM logs.
