 There are multiple Python kernels available that work in the browser. Two popular ones are [Pyodide] and [`Xeus-Python`]. The latter allows you to install packages from `conda-forge` during build time, making them immediately available on your website. In this example, `Xeus-Python` will be used.
 
-When you have installed `jupyterlite-xeus-python`, the kernel will automatically be included in the build without any configuration. However, the default kernel only comes with `numpy`, and we want to make sophisticated interactive content, for example with `matplotlib` and `ipywidgets`. `Xeus-Python` can install these packages itself with `conda`. All we need to do is give it a list of the packages we want installed. To this end, we need to make a configuration file for `jupyterlite` containing settings that will be passed to `Xeus-Python`. The configuration file needs to be in JSON format, and needs to be placed in the root directory of your repository (where `requirements.txt` and `.gitlab-ci.yml` live). In this file, we can specify which packages need to be installed in the kernel as follows:

 For `requirements.txt` add the following lines:
 ```
 --extra-index-url https://gitlab.tudelft.nl/api/v4/projects/11239/packages/pypi/simple
-sphinx-thebe == 0.2.1000
+sphinx-thebe ~= 0.9.9
 ```
 This will download the correct version of the sphinx extension when the book is build on the server (which loads the required packages from `requirements.txt`)
 
 Afterwards, this sphinx extension needs to be enabled in your book. This can be done by adding the following lines to `_config.yml`:
 
 ```
-launch_buttons:
-  thebe: true

-By `launch_buttons` you initiate the {fa}`rocket` --> {guilabel}`Live Code` on the top right corner of every page generated from a `.ipynb` file. The `html_js_files` link calls for some required javascript files. `use_thebe_lite` makes sure you initiate our adapted sphinx thebe extensions. The `exclude_patterns` makes sure you import all files so that they can be accessed from your code, except for the files matching the patterns shown.
