How to use:
DirectoryIndex index.html index.php /_h5ai/public/index.php
h5ai is a modern file indexer for HTTP web servers with focus on your files. Directories are displayed in a appealing way and browsing them is enhanced by different views, a breadcrumb and a tree overview. Initially h5ai was an acronym for HTML5 Apache Index but now it supports other web servers too.
See the demo directory with most features enabled. A reduced example and my actual use case is the release directory for the projects on this page.
