 - [Community containers](https://github.com/nextcloud/all-in-one/tree/main/community-containers#community-containers)
 <details><summary>And much more:</summary>
 
+### User-Friendly Web Interface
+
 - Simple web interface included that enables easy installation and maintenance
 - [Easy updates included](https://github.com/nextcloud/all-in-one#how-to-update-the-containers)
 - Update and backup notifications included
+- Included containers easy to debug by having the possibility to check their logs directly from the AIO interface
+
+### Daily Backup and Easy Restore
+
 - Daily backups can be enabled from the AIO interface which also allows updating all containers, Nextcloud and its apps afterwards automatically
 - Instance restore from backup archive via the AIO interface included (you only need the archive and the password in order to restore the whole instance on a new AIO instance)
+- Adjustable backup path or remote borg repository from the AIO interface (good to put the backups e.g. on a different drive if using a local backup path)
+- Possibility included to also back up external Docker Volumes or Host paths (can be used for host backups)
+- Borg backup can be completely managed from the AIO interface, including backup creation, backup restore, backup integrity check and integrity-repair
+- Other forms of [remote backup](https://github.com/nextcloud/all-in-one#are-remote-borg-backups-supported) are indirectly possible
+- Updates and backups can be [run from an external script](https://github.com/nextcloud/all-in-one#how-to-stopstartupdate-containers-or-trigger-the-daily-backup-from-a-script-externally). See [this documentation](https://github.com/nextcloud/all-in-one#how-to-enable-automatic-updates-without-creating-a-backup-beforehand) for a complete example.
+- Migration from any former Nextcloud installation to AIO is possible. See [this documentation](https://github.com/nextcloud/all-in-one/blob/main/migration.md). 
+- Migration in the other direction (e.g. from AIO to a VM-based installation) is also possible.
+
+### Performance Optimizations
+
 - APCu as local cache
 - Redis as distributed cache and for file locking
 - Postgresql as database
 - PHP-FPM with performance-optimized config (e.g. Opcache and JIT enabled by default)
+- Brotli compression enabled by default for javascript, css and svg files which reduces Nextcloud load times
+- HTTP/2 and HTTP/3 enabled
+- "Pretty URLs" for Nextcloud are enabled by default (removes the index.php from all links)
+- Video previews work out of the box and when Imaginary is enabled, many recent image formats as well!
+
+### Security
+
 - A+ security in Nextcloud security scan
+- Automatic TLS included (by using Let's Encrypt)
+- By default confined (good for security) but can [allow access to additional storages](https://github.com/nextcloud/all-in-one#how-to-allow-the-nextcloud-container-to-access-directories-on-the-host) in order to enable the usage of the local external storage feature
+- Almost all included containers Alpine Linux based (good for security and size)
+- Many of the included containers run as non-root user (good for security)
+- Many of the included containers have a read-only root-FS (good for security)
+- Included containers run in its own docker network (good for security) and only really necessary ports are exposed on the host
+- Can be used with [Docker rootless](https://github.com/nextcloud/all-in-one/blob/main/docker-rootless.md) (good for additional security)
+- [Fail2Ban can be added](https://github.com/nextcloud/all-in-one#fail2ban)
+
+### Compatibility
+
 - Ready to be used behind existing [Reverse proxies](https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md)

 - Ready for big file uploads up to 10 GB on public links, [adjustable](https://github.com/nextcloud/all-in-one#how-to-adjust-the-upload-limit-for-nextcloud) (logged in users can upload much bigger files using the webinterface or the mobile/desktop clients since chunking is used in that case)
 - PHP and web server timeouts set to 3600s, [adjustable](https://github.com/nextcloud/all-in-one#how-to-adjust-the-max-execution-time-for-nextcloud) (important for big file uploads)
 - Defaults to a max of 512 MB RAM per PHP process, [adjustable](https://github.com/nextcloud/all-in-one#how-to-adjust-the-php-memory-limit-for-nextcloud)
-- Automatic TLS included (by using Let's Encrypt)

 - Only one domain and not multiple domains are required for everything to work (usually you would need to have one domain for each service which is much more complex)
-- [Adjustable location](https://github.com/nextcloud/all-in-one#how-to-change-the-default-location-of-nextclouds-datadir) of Nextcloud's datadir (e.g. good for easy file-sharing with host system on Windows and MacOS)
