 ### Detect language
 
-If you have a list of texts to detect, a possible way is to instanciate 
-once and then to evaluate your list.
+Instanciate a detector and pass a text.
+
+Then, you can get the detected language.
 
 ```php
 require_once 'vendor/autoload.php';
 
-$text = 'My sentence is in english';
+$text = 'My tailor is rich and Alison is in the kitchen with Bob.';
 
 $detector = new LanguageDetector\LanguageDetector();
 
 $language = $detector->evaluate($text)->getLanguage();
 
 echo $language; // Prints something like 'en'
 ```
+
+Once it's instanciated, you can check for multiple texts.
+
+```php
+require_once 'vendor/autoload.php';
+
+// An array of texts to evaluate
+$texts = [
+    'My tailor is rich and Alison is in the kitchen with Bob.',
+    'Mon tailleur est riche et Alison est dans la cuisine avec Bob'
+];
+
+$detector = new LanguageDetector\LanguageDetector();
+
+foreach ($texts as $key => $text) {
+
+    $language = $detector->evaluate($text)->getLanguage();
+
+    echo sprintf(
+        "Text %d, language=%s\n",
+        $key,
+        $language
+    );
+}
+
+```
+
+Would output something like:
+
+```sh
+Text 0, language=en
+Text 1, language=fr
+```
