 Adding or updating JavaScript libraries
 ---------------------------------------
 If you need to add a new library, or update the version of a library, you will
-need to have `npm` installed.
+need to have `jupyterlab` installed (it provides the `jlpm` command).
 
-To install npm on OS X, use Homebrew to install node (npm will be installed
-along with node)::
-
-    brew update
-    brew install node
-
-To install npm on Linux with apt-get, use::
-
-    apt-get update
-    apt-get install node
-    apt-get install npm
-

+``nbgrader/server_extensions/formgrader/static/node_modules``.
 Usually, JavaScript libraries installed in this way include a lot of extra files
 (e.g. tests, documentation) that we don't want to commit to the nbgrader
 repository. If this is the case, please add these files to the
