+The SpamSpan module obfuscates email addresses to help prevent spambots from
+collecting them.  It implements the technique at http://www.spamspan.com
+
+The problem with most email address obfuscators is that they rely upon
+JavaScript being enabled on the client side.  This makes the technique
+inaccessible to people with screen readers.  SpamSpan however will produce
+clickable links if JavaScript is enabled, and will show the email address as
+<code>example [at] example [dot] com</code> if the browser does not support
+JavaScript or if JavaScript is disabled.
+
+Installation
+------------
+
+1. Create a directory in your Drupal modules directory (probably
+   sites/all/modules/) called spamspan and copy all of the module's
+   files into it.
+
+2. Go to the Modules administration page (admin/modules), and enable the
+   spamspan module (under Input Filters)
+
+3. Go to the Text Formats Configuration page (admin/config/content/formats)
+   and configure the desired input formats to enable the filter.
+
+4. Rearrange the Filter processing order to resolve conflicts with other 
+   filters.  NB: To avoid problems, you should at least make sure that the 
+   SpamSpan filter has a higher weighting (greater number) than the line break 
+   filter which comes with Drupal ("Convert line breaks into HTML" should come 
+   above SpamSpan in the list of Enabled filters).  If you use HTML filter 
+   ("Limit allowed HTML tags"), you may need to make sure that <span> is 
+   one of the allowed tags. Also, URL filter ("Convert URLs into links") must 
+   come after SpamSpan.
+
+5. (optional) Set available options under "Filter Settings". 
+
