- Built-in [MangaDex](https://mangadex.org/) downloader
 - Supports [plugins](https://github.com/hkalexling/mango-plugins) to download from thrid-party sites
 - The web reader is responsive and works well on mobile, so there is no need for a mobile app

 - `scan_interval_minutes`, `thumbnail_generation_interval_hours` and `db_optimization_interval_hours` can be any non-negative integer. Setting them to `0` disables the periodic tasks
 - `log_level` can be `debug`, `info`, `warn`, `error`, `fatal` or `off`. Setting it to `off` disables the logging
 - You can disable authentication by setting `disable_login` to true. Note that `default_username` must be set to an existing username for this to work.
+- By setting `cache_enabled` to `true`, you can enable an experimental feature where Mango caches library metadata to improve page load time. You can further fine-tune the feature with `cache_size_mbs` and `cache_log_enabled`.
