 - [☕ Gitea Installer](#gitea-installer-script)

 ## Nextcloud installer script
+
 The lab guide is condensed into a script so Nextcloud can be installed  in less than 3 minutes by executing only one command and setting the admin user credentials.

 The following components will be set up and installed automatically:

-* php settings
-* sendmail email settings
-* cronjob
-* prettier URLs without index.php
-* Memcaching with redis and APCu
-* Client Push (notify_push)
-* `nextcloud-update` script
-* the default phone region will be set to `DE`, you may change it after the installation to a different setting
-
