 ## Quickstart
 This quickstart assumes users have already installed fedeca in a conda environment.  
 
+We recommend users to first install ipython (`pip install ipython`) or jupyter,
+and to copy-paste and run the content of the blocks sequentially either in the
+ipython shell or in a jupyter notebook.  
+
+(Don't forget to make sure the `ipython` interpreter being called is the one from the fedeca
+conda environment by calling `which ipython`. In the case it is not the correct one
+running `hash -r` usually does the trick. Similarly when using ``jupyter`` make sure
+the kernel used is the python interpreter from the conda environment (see i.e. this [stackoverflow question](https://stackoverflow.com/questions/39604271/conda-environments-not-showing-up-in-jupyter-notebook>)))

 FedECA tries to mimic scikit-learn API as much as possible with the constraints
 of distributed learning.
 The first step in data science is always the data.

 return type of the substra opener is indeed a pandas.dataframe but let's keep
 it simple in this quickstart.

 Here we will use fedeca utils which will generate some synthetic survival data
 following CoxPH assumptions:
