 ## How to run using Docker
 
 See [grocy/grocy-docker](https://github.com/grocy/grocy-docker) for instructions.
 
 ## How to update
-Just overwrite everything with the latest release while keeping the `data` directory, check `config-dist.php` for new configuration options and add them to your `data/config.php` (the default from values `config-dist.php` will be used for not in `data/config.php` defined settings). Just to be sure, please empty `data/viewcache`.

Just to be sure, please empty `data/viewcache`.
 
-If you run grocy on Linux, there is also `update.sh` (remember to make the script executable, `chmod +x update.sh` and ensure that you have `unzip` installed) which does exactly this and additionally creates a backup (`.tgz` archive) of the current installation in `data/backups` (backups older than 60 days will be deleted during the update).

 ## Localization
 grocy is fully localizable - the default language is English (integrated into code), a German localization is always maintained by me.
 You can easily help translating grocy at https://www.transifex.com/grocy/grocy, if your language is incomplete or not available yet.
 (Language can be changed in `data/config.php`, e. g. `Setting('CULTURE', 'it');`)
 
-### Maintaining your own localization
-As the German translation will always be the most complete one, for maintaining your localization it would be easiest when you compare your localization with the German one with a diff tool of your choice.
+The [pre-release demo](https://demo-prerelease.grocy.info) is available for any translation which is at least 80 % complete and will pull the translations from Transifex 10 minutes past every hour, so you can have a kind of instant preview of your contributed translations. Thank you!
 
 ## Things worth to know
 
 ### REST API & data model documentation
 See the integrated Swagger UI instance on [/api](https://demo.grocy.info/api).
 
-### Barcode readers
+### Barcode readers & camera scanning
 Some fields also allow to select a value by scanning a barcode. It works best when your barcode reader prefixes every barcode with a letter which is normally not part of a item name (I use a `$`) and sends a `TAB` after a scan.
 
+Additionally it's also possible to use your device camera to scan a barcode by using the camera button on the right side of the corresponding field (powered by [QuaggaJS](https://github.com/serratus/quaggaJS), totally offline / client-side camera stream processing).
