-Automated Bash installer script for configuring unattended updates on Ubuntu 24.04 Server.
+Automated configuration for **unattended upgrades** on Ubuntu 24.04 Server.  
+Security patches, apt updates and weekly maintenance — fully automatic.
 
-> **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**  
+Set it once → it updates itself.
 
-> **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:
+## Automatic Defaults
+
+| Setting | Enabled |
+|---|---|
+| Security & package upgrades | ✔ |
+| Weekly unattended execution | ✔ Sundays @ 04:00 |
+| Interactive prompts | ❌ None — unattended mode |
+
+---
+
+## Cron Job Location (Important)
+
+This script does **not** create a user cron via `crontab -e`.
+
+Instead, it deploys a root‑level update scheduler here:
 
 ```
-#
-# 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"
+/etc/cron.d/updatesystem
 ```
 
-### Preparing
-Update your package index before running the installer:
+Meaning:
+
+✔ runs as **root**  
+✔ independent of user accounts  
+✔ persistent across reboots  
+✔ zero interactive maintenance needed
+
+Modify schedule:
 
 ```
-sudo apt update -y
+sudo nano /etc/cron.d/updatesystem
 ```
 
-### Download the Script
-Clone the repository from your Git server:
