 Optional Packages
 -----------------
 
-Optionally, you can install timezonefinder to allow for automatic timezone detection when performing Enviornment Analysis.
-This can be done by running the following line of code in your preferred terminal:
+The EnvironmentAnalysis class requires a few extra packages to be installed.
+In case you want to use this class, you will need to install the following packages:
+
+- `timezonefinder` : to allow for automatic timezone detection,
+- `windrose` : to allow for windrose plots,
+- `ipywidgets` : to allow for GIFs generation,
+- `jsonpickle` : to allow for saving and loading of class instances.
+
+You can install all these packages by simply running the following lines in your preferred terminal:
 
 .. code-block:: shell
 
-    pip install timezonefinder
+    pip install rocketpy[env_analysis]
+
+
+Alternatively, you can instal all extra packages by running the following line in your preferred terminal:
+
+.. code-block:: shell
 
-Keep in mind that this package is not required to run RocketPy, but it can be useful if you want to perform Environment Analysis.
-Furthermore, timezonefinder can only be used with Python 3.8+.
+    pip install rocketpy[all]
