Why Write It Down?
Documentation turns experience into something reusable.
Technical work is easy to forget when the problem is solved and the terminal window closes.
Writing down the reasoning, failures, commands, architecture decisions, and lessons learned creates something that can be reused later.
These writeups are meant to be useful to me, useful to other people learning similar systems, and useful as evidence of how I approach technical work.
