+Indicoio-python will look first for $HOME/.indicorc then ./.indicorc for the optional configuration file. The indicorc can be used to set an authentication username and password as well as the private cloud hostname, so they don't need to be specified for every call. All sectiions are optional.
+
+Here is an example of a valid indicorc file:
+
+```
+[auth]
+username = test@example.com
+password = secret
+
+[private_cloud]
+hostname = example.indico.io
