How to use this hub
- Open one category for broad navigation when you are exploring a new tool area.
- Jump straight to a specific cheatsheet when you need a command pattern during implementation.
- Use these references alongside notebooks and project work, not as a separate study track.
The best use case for this section is active work: terminal open, docs nearby, and just enough reference material to keep momentum.
