Using Markdown / obsidian to navigate

I want to use markdown to navigate large directories, on the order of terabytes, for example, of images and notes, potentially in a shared space.

Obsidian is great, especially for creating these notes, but I don’t want to have to index etc, especially if multiple users are wanting to use it just for navigation.

Do you have a recommended stripped-down markdown viewer that is useful for this kind of thing? Or is there a way to configure Obsidian to do this?

Can you describe what you want in more detail? I’m not sure what you mean by not wanting to index.

If you mean you want automatically-created lists of links, you might try the Waypoint or Zootelkeeper plugins (I’ve probably spelled it wrong, so search “Zoot”), or search “index” or “MOC” to see if there are other plugins that do similar things.
