 MoneyGo requires HTTPS or FCGI (no HTTP). Before starting the server, you will
 want to edit the example configuration file

-of the config file.
+'[http]' section of the config file.
 
 Then, assuming you're in the same directory you ran the above installation
 commands from, running MoneyGo is as easy as:
 
-	./bin/moneygo -config src/github.com/aclindsa/moneygo/example_config.ini
+	./bin/moneygo -config src/github.com/aclindsa/moneygo/internal/config/example_config.ini
 
 You should then be able to explore MoneyGo by visiting https://localhost:8443 in
 your browser. Editing the configuration file supplied will allow you to modify
