A field guide, not a firehose

IT and security, explained the way someone should have explained them to you first.

Root & Route is written for people at the actual start of the trail — career switchers, students, and first-line engineers — who are tired of tutorials that assume you already know the thing they're teaching.

Basecamp — no prior knowledge needed
Trailhead — the basics, applied
Ridge — connecting the concepts
Summit — practitioner depth
The route

Four waypoints. Walk them in order or jump ahead.
