+The new domain process (NDP) is a process that evaluates new domains for
+inclusion in the search engine index.   
+
+It visits the root document of each candidate domain, ensures that it's reachable,
+verifies that the response is valid HTML, and checks for a few factors such as length
+and links before deciding whether to assign the domain to a node.
+
+The NDP process will assign new domains to the node with the fewest assigned domains.
+
+The NDP process is triggered with a goal target number of domains to process, and
+will find domains until that target is reached.  If e.g. a goal of 100 is set,
+and 50 are in the index, it will find 50 more domains.
