+## Adding Nodes
+Nodes that are added to specify the route that a call will use to reach it's destination can follow one of three formats:
+
+### Simple Key Search
+In Example 1 below, the first node added to the route uses a simple key search. In this case, after calling the base URL, CRESTer will search the returned json for a key called "constellations" and calls the URL in that item's "href".
+
+### Key-Value Search
+Also demonstrated in Example 1 is adding a key-value search node, shown by the second call to node(). In the example, the node is told to search for a key called "name" that has a value of "Joas".
