There are several parts of this example which combine to make it extremely easy to create new plots in the wiki farm:
1. localtest.me is a public domain name which is configured so that all sub-domains point at 127.0.0.1, the loopback address of your own computer.
2. our proxy service is configured to accept requests for all domains and sub-domains and direct them to our web service where federated wiki runs.
3. the wiki contains a config.json sets into farm mode which accepts requests for all sub-domains of localtest.me.
These three things together allow the creation of new wikis by simply choosing a new sub-domain in our web browser.
