A small reference notebook
Write labels that help a reader
Name the result
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.
Keep examples honest
An example should resemble the task it explains, while staying clearly separate from real personal information. Use a small example that makes one point. Additional details are helpful only when they change how the reader understands or carries out the task.
Read the page aloud
Reading a short page aloud can reveal repeated phrases and missing connections. Listen for the point where a sentence becomes difficult to follow. Often the repair is a clearer verb or a more concrete subject, followed by a check that the meaning has stayed the same.
