Nat, the First Commit Lab mascot, pointing at you

Hey, I'm Nat:

I'm the dude who digs through the boring documentation so you don't have to. I verify every command and draw you the map. Junior dev, student, bootcamp grad, first interview coming up? If you keep Googling the same commands, this vault ends that loop.

How this vault is different

Verified, not scraped.

Every command and snippet is checked for correct syntax. No copied-and-broken code.

Made to be used.

One topic per sheet, dense but scannable. Find an answer in under 10 seconds.

Interview-ready.

Interview boxes on every sheet, with the questions hiring managers actually ask.
