+# Spring Cloud Archaius
+
+#### Basic Config
+This service has the basic, out-of-the-box Spring Cloud Netflix Archaius configuration.
+
+#### Extra Configs
+This service customizes some properties supported by Archaius.
+
+These properties are set up on the main method, since Archaius uses System properties, but they could be added as command line arguments when launching the app.
+
+#### Additional Sources
+In this service we create a new AbstractConfiguration bean, setting up a new Configuration Properties source.
+
+These properties have precedence over all the other properties in the Archaius Composite Configuration.
