+
+## Description:
+
+What is **Securimage**?
+
+Securimage is a PHP class that is used to generate and validate CAPTCHA images.
+    
+The classes uses an existing PHP session or creates its own if none is found to
+store the CAPTCHA code.  In addition, a database can be used instead of 
+session storage.
+    
+Variables within the class are used to control the style and display of the
+image.  The class uses TTF fonts and effects for strengthening the security of
+the image.
+    
+It also creates audible codes which are played for visually impared users.
+
+## UPGRADE NOTICE:
+
+**3.6.3 and below:**
+Securimage 3.6.4 fixed a XSS vulnerability in example_form.ajax.php.  It is
+recommended to upgrade to the latest version or delete example_form.ajax.php
+from the securimage directory on your website.
+
+**3.6.2 and above:**
+
+If you are upgrading to 3.6.2 or greater *AND* are using database storage,
+the table structure has changed in 3.6.2 adding an audio_data column for
+storing audio files in the database in order to support HTTP range
+requests.  Delete your tables and have Securimage recreate them or see
+the function createDatabaseTables() in securimage.php for the new structure
+depending on which database backend you are using and alter the tables as
+needed.  If using SQLite, just overwrite your existing securimage.sq3 file
+with the one from this release.
+
+*If you are not using database tables for storage, ignore this notice.*
