+# NodeName-Core
+This repository is part of the NodeName Project, a simple to use and very flexible Nameserver implementation for NodeJS.
+
+## What does this NodeName-Core contain?
+
+NodeName-Core is responsible for several things:
+
+- parsing incoming DNS requests
+- serializing outgoing answers
+- providing storage backend API definition
+
+## API
+
+``` JavaScript
+   const Core = new DnsCore();
+   Core.addStorage(new AnyStoragePlugin(options), timeout?);
+   // One or multiple storage plugins
+   // All Storage engines are requested at the same time all their results will be processed
+   // Optionally an timeout can be defined after wich this storage engine will be ignored
+   // If no others answer an error is returned in Response
+
+   Core.addMonitoring(new MonitoringPlugin(options));
+   // Async called Monmitoring plugin.
+
+   Core.addListener(new ListenetPlugin(options));
+
+   // The question plugin can handle on or more Questions and needs to
+   // make shure, that it creates the desired output. It is responsible
+   // for handeling the question and optionally add additional questions
+   // to be resolved.
+   Core.addQuestionHandler(new QuestionPlugin(options));
+```
