It’s also ludicrous how easy it is to setup. The website claims it takes minutes. It took minutes, but only because I sat there with it working trying to work out how I finished the config. After cursing the brevity of the documents I realised that they were complete and it was actually running. Total setup was less than 10 minutes, maybe even 5 minutes.

The steps are basically:

“Step 1: Sign up for an account

Step 2: Add a machine to your network

Step 3: Add another machine to your network”
