+The javascript libraries should be installed in the `libs` directory.
+Either make a `libs` directory here or a symbolic link to somewhere else.
+
+Currently, libs should contain:
+
+    bootstrap-4.1.3
+    codemirror-5.40.2
+    DataTables
+    fontawesome-free-5.3.1-web
+    MathJax-2.7.5
+
+and the files:
+
+    jquery-3.3.1.min.js
+    popper.min.js
+
+The DataTables directory was generated by https://www.datatables.net/download/
+Select: 
+- styling: bootstrap4
+- packages: datatables
+- extensions: responsive
+This will generate a zip that contains the directory `DataTables`. Expand the zip into `libs`.
