+Classes are installed in: `/usr/share/php/SpojeNet/SmsInput`
+Autoloader: `/usr/share/php/SpojeNet/SmsInput/autoload.php`
+
+To use in your PHP code:
+
+```php
+require_once '/usr/share/php/SpojeNet/SmsInput/autoload.php';
+```
+
+The autoloader is automatically generated by `phpab` during package build and 
+includes all package classes with proper dependency loading.
+
+**Note:** This package NO LONGER ships vendor/autoload.php from Composer.
+Use the Debian autoloader instead for proper system integration.
+
+Installation
+------------
+
+For Debian, Ubuntu & friends please use repo:
+
+```shell
+sudo apt install lsb-release wget
+echo "deb http://repo.vitexsoftware.cz $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/vitexsoftware.list
+sudo wget -O /etc/apt/trusted.gpg.d/vitexsoftware.gpg http://repo.vitexsoftware.cz/keyring.gpg
+sudo apt update
+sudo apt install Sms-Input
+```
+
+Composer Integration
+--------------------
+
+If using Composer in your application, you can reference the Debian package:
+
+```json
+{
+    "require": {
+        "deb/Sms-Input": "*"
+    },
+    "repositories": [
+        {
+            "type": "path",
+            "url": "/usr/share/php/SpojeNet/SmsInput",
+            "options": {
+                "symlink": true
+            }
+        }
+    ]
+}
+```
+
+Migration from Composer vendor/autoload.php
+--------------------------------------------
+
+If you're migrating from Composer's autoloader, replace:
+
+```php
+require_once __DIR__ . '/../vendor/autoload.php';
+```
+
+with:
+
+```php
+require_once '/usr/share/php/SpojeNet/SmsInput/autoload.php';
+```
+
+This ensures you're using the system-wide Debian packages instead of bundled dependencies.
