+Creating a Node allocates basic resources such as the data directory and returns the node
+in its INITIALIZING state. Lifecycle objects, RPC APIs and peer-to-peer networking
+protocols can be registered in this state. Basic operations such as opening a key-value
+database are permitted while initializing.
+
+Once everything is registered, the node can be started, which moves it into the RUNNING
+state. Starting the node starts all registered Lifecycle objects and enables RPC and
+peer-to-peer networking. Note that no additional Lifecycles, APIs or p2p protocols can be
+registered while the node is running.
+
+Closing the node releases all held resources. The actions performed by Close depend on the
+state it was in. When closing a node in INITIALIZING state, resources related to the data
+directory are released. If the node was RUNNING, closing it also stops all Lifecycle
+objects and shuts down RPC and peer-to-peer networking.
+
+You must always call Close on Node, even if the node was not started.
