1. Choose the first knowledge gap.
Review recurring questions, handoff needs or operating tasks. Identify current notes, code, product documentation and the people who can verify them.
Process
Check the guide with someone who needs to use it.
The work starts with the audience, the task and reliable source material.
2. Agree scope and access.
Decide what belongs in public, internal or restricted guidance. Keep secrets out of examples and name the owner approving technical details.
3. Draft a useful structure.
Write the explanation or procedure around the reader's starting point. Include prerequisites, safe examples, expected results and relevant limits.
4. Verify the task.
Ask a representative reader to follow the guide in an appropriate environment. Record unclear steps and check links, examples and failure instructions.
5. Publish with an owner.
Agree review dates or change triggers, contribution rights and a correction route. Hand over the source files and publishing instructions in the agreed format.
Prepare the documentation checklist or discuss a first scope.
