 By default, URLs in CodeIgniter are designed to be search-engine and human-friendly. Rather than using the standard
 "query-string" approach to URLs that is synonymous with dynamic systems, CodeIgniter uses a **segment-based** approach::
 
-    example.com/news/article/my_article
+    https://example.com/news/article/my_article
 
 Your URLs can be defined using the :doc:`URI Routing </incoming/routing>` feature with flexibility.
 
 The :doc:`URI Library <../libraries/uri>` and the :doc:`URL Helper <../helpers/url_helper>` contain functions that make it easy to work with your URI data.
