About

Useful things,
written down.

Field notes is a small collection of technical reference pages. Each note focuses on one idea and keeps the examples close to the explanation.

What belongs here

Web fundamentals, file organisation and everyday maintenance. These are working notes rather than product announcements. They are intended to be readable without creating an account or loading a large application.

How to read the notes

Start with the question a note addresses, then try its checks in an environment you understand. Examples are deliberately small. A production system may have additional requirements.
