🧠 What this thing actually is — 30 sec
A searchable, copy-paste-ready cookbook of commands that IT people, sysadmins, and home-lab tinkerers use every day. Built by a working technician for working technicians.
Think of it like Stack Overflow’s answers — already filtered, organized into folders, with one-click copy buttons — instead of digging through 20 forum threads to find that one command you need.
Cheat sheet = a quick-reference card. Command = the text you type into a Linux/Windows terminal to make things happen.

🧱 The cool .bcbc pack format (the share-friendly trick)
Each “pack” is a small text file ending in .bcbc. You can:
Export a pack → share with a friend (just a tiny file)
Import someone else’s pack → adds their commands to your library
Make your own pack → fill in commands you personally use, share with your team
Duplicate-pack detection → if you import the same pack twice, no double entries
The play: build a custom pack for your specific job (e.g. “our company’s deploy commands”) → email it to a new hire → they import it → instantly trained on your stack.
