-#### Pyodide kernel:
-
-- Is based on [Pyodide](https://github.com/pyodide/pyodide)
-- Uses [IPython](https://github.com/ipython/ipython) for the code execution (access to IPython magics, support for the inline Matplotlib backend, *etc*)
-- Provides a way to dynamically install packages with ``piplite`` (**e.g.** ``await piplite.install("ipywidgets")``)
-- **Does not support** sleeping with ``from time import sleep``
-- **Does not support** pre-installing packages

+You can install a specific kernels and extra packages by adding them to the ``environment.yml`` file.
 
 For example, if you want to create a JupyterLite deployment with NumPy and Matplotlib pre-installed, you would need to edit the ``environment.yml`` file as following:
 
 ```yml
-name: xeus-python-kernel
+name: xeus-kernel

   - https://repo.mamba.pm/emscripten-forge

+Instead, if you'd like to use the R kernel and the coursekata package pre-installed, you can edit the ``environment.yml`` as following:
+
+```yml
+name: xeus-kernel
+channels:
+  - https://repo.mamba.pm/emscripten-forge

 Only ``no-arch`` packages from ``conda-forge`` and packages from ``emscripten-forge`` can be installed.
 - **How do I know if a package is ``no-arch`` on ``conda-forge``?** ``no-arch`` means that the package is OS-independent, usually pure-python packages are ``no-arch``. To check if your package is ``no-arch`` on ``conda-forge``, check if the "Platform" entry is "no-arch" in the https://beta.mamba.pm/channels/conda-forge?tab=packages page. If your package is not ``no-arch`` but is a pure Python package, then you should probably update the feedstock to turn your package into a ``no-arch`` one.

 - **How do I know if my package is on ``emscripten-forge``?** You can see the list of packages pubished on ``emscripten-forge`` [here](https://beta.mamba.pm/channels/emscripten-forge?tab=packages). In case your package is missing, or it's not up-to-date, feel free to open an issue or a PR on https://github.com/emscripten-forge/recipes.
