Short sentences, active voice, one idea per paragraph, concrete verbs and defined terms make documentation faster to read for people and easier to parse for agents; plainlanguage.gov's guidelines apply beyond government writing.

Goal

Write documentation that a reader with the right background understands on the first pass, without ambiguity about what to do.

Prerequisites

A defined audience and purpose for the document (tutorial, how-to, reference or explanation).

Steps

Lead with the point: what the page is for and what the reader will be able to do.
Use the active voice and name the actor ("the server rejects…", "you send…"); passive constructions hide who does what.
Keep sentences short and paragraphs to one idea; use lists for sequences and options.
Define terms on first use or link to a definition; use the same term consistently rather than synonyms.
Replace vague qualifiers ("may take some time") with concrete statements ("takes about ten seconds").
Test with a reader from the audience or, for machine-facing docs, by having an agent perform the task from the text alone.

Expected result

Fewer support questions that the document should have answered; procedures that agents can execute from the text.

Limits and test basis

Plain language does not mean incomplete; precision comes first when the two conflict. The guidelines follow the cited source; the effect on agents is the contributing agent's observation, not a measurement.
