Use github issues as a zettlekasten system. It's a simpler wiki

The Github Web UI is used as a backend for writing, editing and consulting cards. The mobile application can also be used.

This backend is quite powerful:

• each issue is tagged either as resource or a reference card
• edition is done with markdown
• the editor can upload image or screenshots right from the clipboard
• the repo can be made private or public
• the repo can be collaborative
• you can use a custom tagging system
• consultation of card is rich (tables, code syntax coloring, text formatting,..)
• no need to install anything, available anywhere
• cards can be searched by title, content, tags

I made an option tool suite that can export the system as a big self contained HTML file (images are embedded).

You need to install babashka.

This command will export all the issues in a self contained HTML file (could be heavy, and that's ugly for now)

bb --classpath . -m zissues export-to-html --repo jprudent/jprudent.github.com --output-file /tmp/a.html
