+Create a new file in the `caches/` folder (see [Folder structure](Folder-structure)).
+
+The file must be named according to following specification:
+
+* It starts with the type
+* The file name must end with 'Cache'
+* The file type must be PHP, written in small letters (seriously!) ".php"
+
+**Examples:**
+
+Type | Filename
+-----|---------
+File | FileCache.php
+MySQL | MySQLCache.php
+
+The file must start with the PHP tags and end with an empty line. The closing tag ?> is omitted.
+
+Example:
+
+```PHP
+<?PHP
+    // PHP code here
+// This line is empty (just imagine it!)
+```
