If you are using docimport for documentation on your site, you can now integrate it with CComment and let visitors comment on your docs.
Go to components -> CComment -> Settings -> click on new. Create a new setting for com_docimport and save it.
Now you'll need to make modifications to the following file: components/com_docimport/views/article/tmpl/item.php . At the end of that file add this code:
<?php JLoader::discover('ccommentHelper', JPATH_ROOT . '/components/com_comment/helpers'); echo ccommentHelperUtils::commentInit('com_docimport', $this->item); ?>
