 ## 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`.
 
-If you run grocy on Linux, there is also `/update.sh` (beside the basic tools `unzip` is needed) which does exact 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. There is one file per language in the `localization` directory, if you want to create a translation, it's best to copy `localization/de.php` to a new one (e. g. `localization/it.php`) and translating all strings there. (Language can be changed in `data/config.php`, e. g. `Setting('CULTURE', 'it');`)
