  * build.sh: to build the docker image (from the Dockerfile at the root of the project)
  * quarto_render.sh: to build the Quarto static website locally
  * scripts/install_requirements.sh: to install ubuntu packages and libraries
  * scripts/micromamba_clean_env.sh: to clean useless files/folders resulting from the micromamba environment creation

The file environment.yml is the init file used to create the micromamba environment.
