I don&#x27;t know. All the places I&#x27;ve worked for so far had close to zero useful documentation, but the reason had nothing to do with people &quot;keeping knowledge for themselves&quot;. It was simply because there&#x27;s always something more important to do than writing documentation and <i>keeping it up to date</i>. Everyone tells themselves and each other that someone has to do it eventually, and in the end, it never happens.
