Labs unlock as you complete them — finish one to open the next. Same checks as sboot test — we compute the verdict.

[ q ]What do I need on my machine?

A Mac, Linux or Windows machine and a terminal — Windows natively, no WSL2. Lab 00 installs Rust and the one extra piece your OS needs — on disk, about 230 MB on Linux, 1 GB on a Mac, 7 GB on Windows (or 1.5 GB with the GNU toolchain). Git is optional.

[ q ]What makes a verified completion meaningful?

Same checks as sboot test — we compute the verdict. That’s what makes it count.

[ q ]Who owns the code I write?

You do. sboot start unpacks it into a folder on your machine and every line stays with you.

[ q ]What does it cost?

Nothing to start — Rust for Beginners is free, every lab of it, and the first 2 labs of Rust for Systems; the rest of the catalog unlocks with a plan. See the plans for what a subscription adds; completed labs stay yours to read even if you cancel.
