+# Conclusion
+
+Hopefully from this Codorial you have seen the power of Firebase - allowing you to concentrate on your application and not worry about other complicated
+ topics, such as authentication. However understanding how to integrate this into your main business logic can seem challenging at first. This Codorial
+ has brought together a number of separate libaries which can be applied to any application context.
+
