 Public networks, as the name implies, can be joined without getting authorization from anyone. All you need is their 16-digit network ID. A public network called [Earth](https://www.zerotier.com/earth.html) (8056c2e21c000001) exists for everyone, but be sure your device is adequately secured and up to date before joining.
 
-Alternatively, you can run your own network configuration controller. This lets you run any network for free. To do this, start with the netconf-service/ subfolder of this project. You'll need to do a bit of system administration work and manually populate a Redis database, but it's not terribly hard if you're into that kind of thing.

 More products and services will be forthcoming.

 The standard implementation uses SQLite3 with the attached schema. A separate service (not included here yet) is used to administrate that database and configure networks.
