Everything else — completeness, structure, tone — matters only insofar as it serves that. ## Know which document you are writing Four kinds, and mixing them is the most common failure: - **Tutorial** — a beginner completes something concrete. Optimised for success, not coverage. No options, no alternatives, no "you could also". - **How-to** — a competent reader accomplishes a specific task. Assumes background, gets to the point. - **Reference** — a reader looks something up. Complete, consistent, scannable, no narrative. - **Explanation** — a reader understands why. Discusses trade-offs and history. A README that opens as a tutorial, becomes reference midway and ends in explanation serves none of the three readers. ## Lead with what it does and who it is for The first paragraph of anything answers: what is this, who is it for, why would I use it rather than the alternative. A reader who cannot answer those in ten seconds leaves, and nothing further you wrote gets read. ## Show, then explain A working example before the prose. Readers scan for the code block, copy it, and read the explanation only when it does not work. Write for that order, because it is what actually happens. Every example must be complete enough to run. An example with an undefined variable or an elided import is worse than none: it costs the reader time before it fails. ## Delete the throat-clearing Cut on sight: "It is important to note that", "Simply", "Just", "Obviously", "As you can see", "In order to" (→ "to"), "utilise" (→ "use"). "Simply" and "just" are the worst — they tell a stuck reader that their difficulty is a personal failing. ## Prefer the concrete "Configure the appropriate settings" tells the reader nothing. "Set `timeout` to at least 30" tells them what to type. If you cannot be specific, you do not yet understand the thing well enough to document it. ## Document the failure cases The reader arrives when something is wrong more often than when it is right. What the common errors mean, what to check first, what is expected behaviour that merely looks like a bug. This section is used more than the happy path and written far less often. ## Say what changed and when Anything with versions needs a changelog entry per user-visible change, and any statement that will go stale — a version number, a limit, a URL — should be somewhere it will be updated, not repeated in six places. ## Editing someone else's Read it once as the intended reader, without fixing anything, and note where you became confused. Those points are the work. Fix them first; grammar and consistency afterwards. A grammatically flawless document that loses the reader in paragraph three has not been improved.
