Hi,

Yes, you have to unzip the zip-file and upload the content to the plugin directory. Then activate the plugin in the settings section and set and password for the webservice. The webservice should then be online. You can check it by calling your wordpress-site with the root-url and append /index.php/dcm_ws/
The response should look like here on my site :
http://wordpress.joomla-dcm.com/index.php/dcm_ws/
Then you can login with DCM client, when you setup your site in DCM configuration there is a connection check button.

Regards
Chris
