Jupyter can't find env Python kernels

I have two envs (+ the default one) that I want to use inside the default Jupyter notebook. If my understanding is correct, that projet should allow that but I can’t see the kernels.

$ conda env list
# conda environments:
#
cadnano                  C:\Users\hadim\Anaconda3\envs\cadnano
cadnano_old              C:\Users\hadim\Anaconda3\envs\cadnano_old
root                  *  C:\Users\hadim\Anaconda3


$ jupyter notebook
[I 12:14:28.044 NotebookApp] [nb_conda_kernels] enabled, 2 kernels found
[I 12:14:28.476 NotebookApp] [nb_conda] enabled
[I 12:14:28.583 NotebookApp] \u2713 nbpresent HTML export ENABLED
[W 12:14:28.583 NotebookApp] \u2717 nbpresent PDF export DISABLED: No module named 'nbbrowserpdf'

[I 12:14:28.829 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

Then :

Should not I see cadnano and cadnano_old as kernels ?

ahah !

Of course you need an ipykernel to use the env as a kernel.

It’s working now after conda install ipykernel.

Maybe you should add a quick note on the README about that.
