title: How to install doxygen with Eclipse
body: <p>I have never used any documentation software. Now I need to use doxygen for JavaScript files.</p>
  
  <p>I am using Eclipse as code editor but don't know how to use doxygen with classic Eclipse for JavaScript files.</p>
  
  <p>I have installed this</p>
  
  <p><a href="http://www.mantidproject.org/Eclipse_Doxygen_Setup" rel="nofollow noreferrer">http://www.mantidproject.org/Eclipse_Doxygen_Setup</a></p>
  
  <p>Then I can see doxygen tab in preferences but it says "add Doxygen version", which I don't know how to add.</p>
  
  <p>What do I do now?</p>
