+File Naming
+===========
+
+Class files must be named in a Ucfirst-like manner, while any other file name
+(configurations, views, generic scripts, etc.) should be in all lowercase.
+
+**INCORRECT**::
+
+	somelibrary.php
+	someLibrary.php
+	SOMELIBRARY.php
+	Some_Library.php
+
+	Application_config.php
+	Application_Config.php
+	applicationConfig.php
+
+**CORRECT**::
+
+	SomeLibrary.php
+	Some_Library.php
+
+	applicationconfig.php
+	application_config.php
+
+Furthermore, class file names should match the name of the class itself.
+For example, if you have a class named `Myclass`, then its filename must
+be **Myclass.php**.
