-sphinx-thebe == 0.2.1000

 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.
