+## Adminer Security settings
+
+To enhance the security of your Adminer installation, we recommend the following settings for Caddy, Apache2, and Nginx:
+
+1. **Rename Adminer File:** Change `adminer.php` to `dbtool.php` to make it less predictable.
+
+2. **Restrict Access by IP:** Only allow access from specific IP addresses.
+
+Below are example configurations for each web server:
+
+### Caddy
+
+```bash
+# Adminer Configuration
+route /dbtool.php* {
+    root * /usr/share/adminer
+    php_fastcgi unix//run/php/php8.2-fpm.sock
+
+    # Define the allowed IP address
+    @allowed {
+        remote_ip your.ip.address.here
+    }
+
+    # Route for allowed IP addresses
+    handle @allowed {
+        file_server
+    }
+
+    # Respond with 403 for any IP address not allowed
+    respond "Access Denied" 403
+}
+```
+
+### Apache .htaccess
+
+```bash
+<Files "dbtool.php">
+    Order Deny,Allow
+    Deny from all
+    Allow from your.ip.address.here
+</Files>
+```
+
+### Nginx
+
+```bash
+location /dbtool.php {
+    allow your.ip.address.here;
+    deny all;
+}
+```
