+
+Automated Bash installer script for configuring unattended updates on Ubuntu 24.04 Server.
+
+> **IMPORTANT**
+> This script configures unattended updates with the following defaults:  
+> - Installs and updates all available packages  
+> - Installs security updates automatically  
+> - Creates a crontab entry to run updates every **Saturday at 04:00**  
+
+> **Optional Features**
+> - Enable removal of unused packages  
+> - Enable automatic reboot if needed  
+> - Enable automatic reboot even if users are logged in  
+
+> **NOTE**
+> Before running the script, decide whether you want to enable the optional features mentioned above. The lines to review in the code are shown below:
+
+```
+#
+# Uncomment the next 2 lines to enable automatic removal of unused packages. This equals apt autoremove.
+#
+# sed -i '/Unattended-Upgrade::Remove-Unused-Dependencies/ s/^\/\/\s*//' "$config2"
+# sed -i 's/Remove-Unused-Dependencies "false"/Remove-Unused-Dependencies "true"/' "$config2"
+
+#
+# Uncomment the next 2 lines to enable automatic reboot
+#
+# sed -i '/Unattended-Upgrade::Automatic-Reboot/ s/^\/\/\s*//' "$config2"
+# sed -i 's/Automatic-Reboot "false"/Automatic-Reboot "true"/' "$config2"
+
+#
+# Uncomment the line below to enable automatic reboot even if users are logged in
+#
+# sed -i '/Unattended-Upgrade::Automatic-Reboot-WithUsers/ s/^\/\/\s*//' "$config2"
+```
+
+### Preparing
+Update your package index before running the installer:
+
+```
+sudo apt update -y
+```
+
+### Download the Script
+Clone the repository from your Git server:
+
+```
+git clone https://git.x-files.dk/server/auto-update-ubuntu.git
+```
+
+```
+cd auto-update-ubuntu
+```
+
+### Usage
+Run the script using:
+
+```
+sudo ./auto-update-ubuntu
+```
+
+### Post-install
+Nothing to do.
