 IPython Documentation
 ---------------------
 
 This directory contains the majority of the documentation for IPython. 
 
 Requirements
 ------------
 The following tools are needed to build the documentation:
 
-sphinx
+sphinx jsdoc
 
 On Debian-based systems, you should be able to run::
 
-    sudo apt-get install sphinx 
+    sudo apt-get install sphinx npm
+    sudo npm install -g jsdoc@"<=3.3.0"
 
 The documentation gets built using ``make``, and comes in several flavors.
 
 ``make html`` - build the API and narrative documentation web pages, this
 is the the default ``make`` target, so running just ``make`` is equivalent to
 ``make html``. 
 
 ``make html_noapi`` - same as above, but without running the auto-generated
 API docs. When you are working on the narrative documentation, the most time
 consuming portion  of the build process is the processing and rending of the
 API documentation. This build target skips that.
 
 ``make pdf`` will compile a pdf from the documentation.
 
 You can run ``make help`` to see information on all possible make targets.
