 * If you have never worked with a command line, or if you just want to give CLIMADA a try, follow the :ref:`simple instructions <install-simple>`.
 * If you want to use the very latest development version of CLIMADA or even develop new CLIMADA code, follow the :ref:`advanced instructions <install-advanced>`.
-  If you want to install `CLIMADA Petals`_, also follow these.
 
 Both approaches are not mutually exclusive.
 After successful installation, you may switch your setup at any time.

+Notes on the CLIMADA Petals Package
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+CLIMADA is divided into two packages, CLIMADA Core (`climada_python <https://github.com/CLIMADA-project/climada_python>`_) and CLIMADA Petals (`climada_petals <https://github.com/CLIMADA-project/climada_petals>`_).
+The Core contains all the modules necessary for probabilistic impact, averted damage, uncertainty and forecast calculations.
+Data for hazard, exposures and impact functions can be obtained from the :doc:`CLIMADA Data API </tutorial/climada_util_api_client>`.
+Hazard and Exposures subclasses are included as demonstrators only.
+
+.. attention:: CLIMADA Petals is **not** a standalone module and requires CLIMADA Core to be installed!
+
+CLIMADA Petals contains all the modules for generating data (e.g., ``TC_Surge``, ``WildFire``, ``OpenStreeMap``, ...).
+New modules are developed and tested here.
+Some data created with modules from Petals is available to download from the :doc:`Data API </tutorial/climada_util_api_client>`.
+This works with just CLIMADA Core installed.
+CLIMADA Petals can be used to generate additional data of this type, or to have a look at the tutorials for all data types available from the API.
+
+Both :ref:`installation approaches <install-choice>` mentioned above support CLIMADA Petals.
+If you are unsure whether you need Petals, you can install the Core first and later add Petals in both approaches.
