-- After cloning or downloading the repository, you'll have to edit the scripts so that they represent your current Nextcloud installation (directories, users, etc.).
-- The scripts assume that Nextcloud's data directory is *not* a subdirectory of the Nextcloud installation (file directory). The general recommendation is that the data directory should not be located somewhere in the web folder of your webserver (usually */var/www/*), but in a different folder (e.g. */var/nextcloud_data*).
-- If you do not want to save the database password in the scripts, remove the variable *dbPassword* and call *mysql* with the *-p* parameter (without password). When calling the scripts manually, you'll be asked for the database password.
+- After cloning or downloading the repository, you'll have to edit the scripts so that they represent your current Nextcloud installation (directories, users, etc.). All values which need to be customized are marked with *TODO* in the script's comments.
+- The scripts assume that Nextcloud's data directory is *not* a subdirectory of the Nextcloud installation (file directory). The general recommendation is that the data directory should not be located somewhere in the web folder of your webserver (usually */var/www/*), but in a different folder (e.g. */var/nextcloud_data*). For more information, see [here](https://docs.nextcloud.com/server/15/admin_manual/installation/installation_wizard.html#data-directory-location-label).
+- However, if your data directory *is* located under the Nextcloud file directory, you'll have to change the scripts so that the data directory is not part of the backup/restore (otherwise, it would be copied twice).
+- The scripts only backup the Nextcloud data directory and can backup a local external storage mounted into Nextcloud. If you have any other external storage mounted in Nextcloud (e.g. FTP), these files have to be handled separately.
+- The scripts assume that you are using MySQL/MariaDB as database for Nextcloud. However, it also supports PostreSQL databases. In this case you have to uncomment the parts of backing up/restoring the database.
+- You should have enabled 4 byte support (see [Nextcloud Administration Manual](https://docs.nextcloud.com/server/15/admin_manual/configuration_database/mysql_4byte_support.html)) on your Nextcloud database. Otherwise, when you have *not* enabled 4 byte support, you have to edit the restore script, so that the database is not created with 4 byte support enabled.
