Problem

Most Python dependencies will be installed when setting up the environment but non-Python dependencies like C++ compilers, LaTeX, and other system applications must be installed separately.

Suggested improvement

This is not actionable.

"most" and "non-Python dependencies like [...] and other system applications" makes impossible for a user to know what to install. Digging through following links is cumbersome.

We may not need to give detailed description, but should mention what to additionally install manually (or ensure it's there) for a reasonable working installation, e.g. (not checked for completeness):

You additionally need

• for a minimal working development environment: a C++ compiler
• for building the docs: Graphviz and a LateX.
