Cheatsheets. Everything You Need. Right When You Need It.
Some things you use every day and still have to look up every time. That's not a knowledge problem — it's a reference problem. These cheatsheets exist to fix it.
Every guide here is organized for fast lookup — not for reading front to back. Commands are grouped logically, explained briefly, and formatted so you can scan and find what you need in seconds. Bookmark the ones you use. Download the PDF. Come back whenever you need a quick reminder.
No fluff. Just the commands, syntax, and patterns that actually matter.
⚙️ How to Use These Cheatsheets
Bookmark first, read second. These are references, not tutorials. Bookmark this page or individual cheatsheets and pull them up when you're mid-project and need a fast answer.
PDFs are available for every cheatsheet. Download them, print them, pin them next to your monitor — whatever works for your workflow.
Each cheatsheet links to the related Guide and Tutorials for when a quick reference isn't enough and you need the full explanation.
