Depending on your OS, this set up with minimal dependencies should take up about `50` mb in space. As your needs expand, you can then manually choose which dependencies to add to your Python environment. For instance, you can install `pandas` if you require to work with spatially enabled DataFrames and `jupyter`, if you need the notebook IDE."
