Using the lessons
You can read and use the lessons to learn. Please don't republish lesson text, diagrams or exercises without permission. Short quotes with a link back are fine.
Running commands
Lessons include commands to run on your own machine. Read each one before you run it, and run them on a computer you control. The Cracked Engineer isn't responsible for changes they make to your system.
Accuracy
We test what we publish, but tools change. Version numbers and outputs in lessons are examples, and yours may differ.
Pro
Pro is not on sale yet. Its billing, cancellation and refund terms will be published here before it opens.
