A small reference notebook
Choose a subject below. Each note can be read on its own.
A page is easier to arrange when its reader has a clear task. Put the information needed for that task near the beginning, then provide supporting detail where it becomes useful. This gives both a quick reader and a careful reader a route through the material.
A useful label tells someone what they will find or what an action will do. Familiar, specific words reduce the need for an extra explanation. When the same action appears in several places, keeping the wording consistent helps a reader recognize it again.
