+## Testing
+
+You can download and test the latest nightly build from https://github.com/nakst/build-essence/releases. Download and extract `Essence.tar.xz`. If you are using VirtualBox, import `Essence.ova`. If you are using Qemu, run 
+
+    qemu-kvm -drive file=drive,format=raw -m 2048 -smp 2 || qemu-system-x86_64 -enable-kvm -drive file=drive,format=raw -m 2048 -smp 2
+
+These builds are configured to run on emulators only, to make testing easier. Builds for real hardware are coming soon :)
