+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+ $this->load->helper('download');
+
+The following functions are available:
+
+force_download('filename', 'data')
+==================================
+
+Generates server headers which force data to be downloaded to your
+desktop. Useful with file downloads. The first parameter is the **name
+you want the downloaded file to be named**, the second parameter is the
+file data. Example
+
+::
+
+ $data = 'Here is some text!';
+ $name = 'mytext.txt';
+ force_download($name, $data);
+
+If you want to download an existing file from your server you'll need to
+read the file into a string
+
+::
+
+ $data = file_get_contents("/path/to/photo.jpg"); // Read the file's contents
+ $name = 'myphoto.jpg';
+ force_download($name, $data);
