    You can now access to the following routes:
        - http://127.0.0.1:8080/
        - http://127.0.0.1:8080/about
        - http://127.0.0.1:8080/wiki/articles
        - http://127.0.0.1:8080/wiki/post
        - http://127.0.0.1:8080/user/login (both GET and POST)
        - http://127.0.0.1:8080/user/logout (only POST)

    Also note that 'textRoutes' and 'userRoutes' use anonymous handlers (for simplicity and to save space).
