It really mostly depends on if other family members will need to edit the wiki.

• If they’ll be only reading dokuwiki might be best - even a single frontpage with all the info nedded.
• If they will be editing then bookstack is way more friendly for non-technical people as is had a full WYSIWYG editor and you don’t have to bother with markdown.

Finally. Seems like I’ll have to take a week off at work.
