Be succinct. More words take longer to read and edit. Be afraid of TLDR

Choose keywords wisely, think of others who will need to find what you write

Dont put more than screeful portion of information on the same page. Use “child page” extensively.

Choose page path (the portion after doku.php?id=) wisely, it is shown in “sitemap” hierachy. Use searchable keywords.

If in doubt - ask seniors where to put this or that memo

Delete mercilessly. We have revisions history, if needed.

Less “How” more “Why”. “How” is volatile, can be found again, but “Why” are the real gems
