Comment:
@xscd I've made a template for it.
It doesn't work with Void out of the box, but it's easy to configure to work with Void.

The only NextDNS commands that work is `nextdns run` so you can start it with something similar:
```
sudo nextdns run \
  -config <your config id> ...
```

In order to use it with Void as system service, you have to put your configuration in 
`/etc/nextdns/nextdns_conf` file and symlink `/etc/sv/nextdnsd` to `/var/service`

To setup the system to use NextDNS as a resolver, un-comment the last line in `/etc/resolvconf.conf` to `name_servers=127.0.0.1` and restart resolvconf with `resolvconf -u` now NextDNS should be used as dns resolver
