+EtherSignal CLI
+
+Quick Start.
+
+1) Launch a geth node if it is not already running.
+geth
+
+2) Attach via the geth command line client
+geth attach
+
+3) Load the ethersignal script.
+> loadScript("ethersignal.js")
+true
+
+Now you can either signal on a position or tally the current signal levels
+for a position.
+
+To Vote on position "0xba32c71348cf21e808067890691aa790486e3a99e628b68cd2bfeb51381bfec1":
