How do I add or reference an article from a manual in a lesson?

We have created an extensive knowledge base full of articles.  Now we would like to develop a course and lessons for new employees based on the content of the articles.  I am not seeing how I add the articles to a lesson.  I know we can copy/paste but we were hoping the reference would be a live link so that if the article is updated, the content of the lesson is also updated.
