==

1. This module depends on the HTMLPurifier and Autoload modules:

 - HTMLPurifier module: http://drupal.org/project/htmlpurifier
 - Autoload module: http://drupal.org/project/autoload

2. Install the module. Detailed instructions can be found at:
   http://drupal.org/documentation/install/modules-themes/modules-5-6

3. Patch the module HTMLPurifier with the patch (compatible with the 6.x-2.4
   release) `patches/htmlpurifier.patch`. If the module is not patched, it will
   not possible to customize the HTMLPurifier library at
   `admin/settings/filters/INPUT_FORMAT_ID/configure`.

    $ cd /path/to/modules/htmlpurifier
    $ patch -p0 --verbose < /path/to/modules/authoring_html/patches/htmlpurifier.patch

4. Optional. Regenerate the HTMLPurifier library configuration schema (you will
   need this if you want to add more hosts to the whitelist of hosts that the
   `iframe` and `script` tags will can refer):

   $ php /path/to/libraries/htmlpurifier/maintenance/generate-schema-cache.php \
   /path/to/modules/authoring_html/HTMLPurifier/schema

5. Read the REAME.txt file for more details for the steps 3 and 4.
