Configure ScreenSteps and Export To Blog

In the Preferences > Web Export pane create a new account using the Movable Type type (1).

For the server you should use the url to your joomla installation followed by /xmlrpc/index.php (2).

http://www.my-joomla-server.com/xmlrpc/index.php

For the user name and password use an account that has permission to publish content on Joomla (3).

Now that you have configured an account you can export any ScreenSteps lesson to your Joomla account. Just select Export > Blog/Web.

In the export dialog you can choose a category (1) to post the lesson to. You can also choose a template that can be used for formatting the lesson (2). Blog HTML Neutral is a good template to use as it will cause your lesson to inherit the look of your Joomla site.

After posting the lesson it will appear in your Joomla site.
