+Step 9: Update your librararies' file names
+*******************************************
+
+CodeIgniter 3.0 only allows library file names to be named in a *ucfirst* manner
+(meaning that the first letter of the class name must be a capital). For example,
+if you have the following library file:
+
+ application/libraries/mylibrary.php
+
+... then you'll have to rename it to:
+
+ application/libraries/Mylibrary.php
+
+The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
+own libraries and core classes.
+
+ application/libraries/MY_email.php
+ application/core/MY_log.php
+
+The above files should respectively be renamed to the following:
+
+ application/libraries/MY_Email.php
+ application/core/MY_Log.php
