Start with the Product Documentation wiki and the linked staging and release decks. Determine with product and development whether the handover belongs in the app, MKDocs, or the wiki, then document the decision and create the detailed follow-up issue. Done means the handover approach is reviewed, agreed, and recorded for the stakeholder.
