Mesh SDK Beaconing Instructions

After some effort, I have managed to build the beaconing example that's missing from the examples.emProject of the ble_mesh_v0.9.1-Alpha SDK. I have this running on the PCA10028 and it's advertising. How do I now use the mesh part? How do I provision this in the mesh network?

I have also had the serial example working with the interactive_pyaci script. However, the documentation just talks for provisioning two serial connected devices. How can this be used to provision the meshed beacon?

Thanks
