 # cbschuld/browser.php
 
-[![Build Status](https://travis-ci.org/cbschuld/Browser.php.png?branch=master)](https://travis-ci.org/cbschuld/Browser.php)
+[![Tests](https://github.com/cbschuld/Browser.php/actions/workflows/tests.yml/badge.svg)](https://github.com/cbschuld/Browser.php/actions/workflows/tests.yml)
 
 Helps detect the user's browser and platform at the PHP level via the user agent
 
 
 ## Installation
 
-You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+### Via Composer (Recommended)
 
-    composer require cbschuld/browser.php
+```bash
+composer require cbschuld/browser.php
+```
+
+For development only:
+```bash
+composer require --dev cbschuld/browser.php
+```
+
+### Direct Download
+
+Download `Browser.php` and include it in your project:
+```php
+require_once 'Browser.php';
+```
 
-If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+## Usage
 
-    composer require --dev cbschuld/browser.php
+### Modern Usage (v2.0+, Recommended)
+
+```php
+use cbschuld\Browser;
 
+$browser = new Browser();
+if ($browser->getBrowser() == Browser::BROWSER_FIREFOX && $browser->compareVersion('10', '>=')) {
+    echo 'You have Firefox version 10 or greater';
+}
+```
 
-## Typical Usage:
+### Legacy Usage (Still Supported)
 
 ```php
+// Works via automatic aliasing - no namespace needed
 $browser = new Browser();
-if( $browser->getBrowser() == Browser::BROWSER_FIREFOX && $browser->getVersion() >=10 ) {
-	echo 'You have FireFox version 10 or greater';
+if ($browser->getBrowser() == Browser::BROWSER_FIREFOX && $browser->getVersion() >= 10) {
+    echo 'You have Firefox version 10 or greater';
+}
+```
+
+### Version Comparison (PHP 8+ Compatible)
+
+```php
+use cbschuld\Browser;
+
+$browser = new Browser();
+
+// Recommended approach for version comparison
+if ($browser->compareVersion('15.0', '>=')) {
+    echo 'Modern browser detected';
+}
+
+// Multiple comparisons
+if ($browser->getBrowser() == Browser::BROWSER_CHROME && 
+    $browser->compareVersion('90', '>=')) {
+    echo 'Modern Chrome detected';
 }
 ```

 In an active project of mine we have a pretty graphically intensive and visually appealing user interface which leverages a lot of transparent PNG files. Because we all know how great IE6 supports PNG files it was necessary for us to tell our users the lack of power their browser has in a kind way.

+# Upgrading from v1.x to v2.0
+
+## Breaking Changes
+
+### PHP Version Requirement
+- **Minimum PHP version**: 8.0+ (was 7.2+)
+- **Reason**: Enables modern PHP features and improved performance
+
+### Namespace Introduction
+- **New namespace**: `cbschuld\Browser`
+- **Migration path**: See usage examples below
+
+### Return Type Declarations
+- Added return type hints to protected methods
+- **Impact**: If you extend the `Browser` class and override protected methods, you'll need to add matching return types
+- **Example**: `protected function checkBrowserEdge(): bool` (was `protected function checkBrowserEdge()`)
+
+## Migration Guide
+
+### For Composer Users
+
+#### Option 1: Use Namespaced Class (Recommended)
+```php
+// Old (v1.x)
+$browser = new Browser();
+
+// New (v2.x) - Recommended
+use cbschuld\Browser;
+$browser = new Browser();
+```
+
+#### Option 2: Keep Using Global Class (Backward Compatible)
+```php
+// Still works in v2.x due to automatic aliasing
+$browser = new Browser();
+```
+
+### For Non-Composer Users
+
+#### Direct Include (Still Works)
+```php
+// Include the root Browser.php file
+require_once '/path/to/Browser.php';
+$browser = new Browser(); // Works via automatic aliasing
+```
+
+#### Manual Namespace Include
+```php
+// Include the namespaced file directly
+require_once '/path/to/src/Browser.php';
+use cbschuld\Browser;
+$browser = new Browser();
+```
+
+### For Class Extenders
+
+If you extend the Browser class, update your method signatures:
+
+```php
+// Old (v1.x)
+class MyBrowser extends Browser {
+    protected function checkBrowserEdge() {
+        // your implementation
+    }
+}
+
+// New (v2.x)
+use cbschuld\Browser;
+
+class MyBrowser extends Browser {
+    protected function checkBrowserEdge(): bool {
+        // your implementation
+    }
+}
+```
+
+## New Features in v2.0
+
+### Improved Version Comparison
+Use the new `compareVersion()` method for PHP 8+ compatible version comparisons:
+
+```php
+$browser = new Browser();
+// Instead of: $browser->getVersion() >= '10.0'
+// Use: $browser->compareVersion('10.0', '>=')
+```
+
+### Enhanced Edge Detection
+- Better support for modern Edge user agents
+- Handles Edge/, Edg/, EdgA/, and EdgiOS/ patterns
+
+## Troubleshooting
+
+### Tests Failing After Upgrade
+- Ensure you're using PHP 8.0+
+- Run `composer install` to get compatible dependencies
+- Update any custom test classes that extend Browser
+
+### Class Not Found Errors
+- For Composer users: Run `composer dump-autoload`
+- For direct includes: Ensure you're including the root `Browser.php` file
+
+### Version Comparison Issues
+- Replace direct version comparisons with `compareVersion()` method
+- This handles PHP 8's stricter type comparison rules
