 ## Usage
 
+1. Use `pwd` to get needed directory, or use `__DIR__` in code.
+```
+$ pwd
+/home/user/project
+```
+
+2. Set your directory path, analyze some folder recursively and create language files.
 ```php
 $analyzer = new \Filipponik\TranslateAnalyzer\Analyzer();
 $analyzer
+    ->setDirectoryPath('/home/user/project')
     // Analyze only .php files
     ->setSuffix('php')
     // Analyze directory ../app
-    ->analyze('../app')
-    // Write to laravel lang files (by default structure)
-    ->writeResultsToLaravelFiles(['en', 'es', 'ch'])
+    ->analyze('app')
+    // Write to laravel 8- file structure
+    ->toLaravel8AndBefore(['en', 'es', 'ch'])
+    // Write to laravel 9+ file structure
+    ->toLaravel9AndAbove(['en', 'es', 'ch'])
     // Or write lang files to selected directory
-    ->writeResultsToFiles('my_super_lang_files');
+    ->writeResultsToFiles('my_lang_files');
