Lower the bar to participate: in-page edit buttons, templates with checklists, and clear instructions for screenshots, code blocks, and links. Support anonymous feedback for sensitive corrections. The easier it is to offer a tiny improvement, the more momentum your knowledge garden will retain.
Shift reviews from gatekeeping to mentorship. Pair new contributors with experienced editors who explain decisions and point to style guides. Replace vague rejections with concrete examples. Celebrate learning in changelogs. Over time, contributors internalize patterns, and quality rises without bottlenecks or bruised egos.
