+Using poliastro on JupyterLab
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ After the release of plotly 3.0, plotting orbits using poliastro is easier than ever.
+
+ You have to install 2 (two) extensions of JupyterLab to make your experience smooth.
+
+   $ jupyter labextension install @jupyter-widgets/jupyterlab-manager
+
+   $ jupyter labextension install @jupyterlab/plotly-extension
+
+ And as the documentation of JupyterLab Extensions states:
+
+    "In order to install JupyterLab extensions, you need to have Node.js version 4 or later installed."
