Guides

Short, practical guides focused on the 20% of knowledge that covers 80% of daily use. No filler — just what you need to be effective.

Available guides

• Terminal essentials — navigate, run commands, and stop being scared of the command line
• Git & GitHub — version control and collaboration without the PhD
• 2026 Security Guide — everyday digital privacy and security: browser, search, passwords, messaging, and defense in depth

Philosophy

These guides are written for builders who use AI tools daily. You don’t need to memorize everything — you need to understand enough that when Cursor or Claude gives you a terminal command, you know what it does and aren’t afraid to run it.
