-This bundle does one simple job: takes dates and gives you friendly "2 hours ago"-type messages. Woh!
+Friendly *ago*/*until* dates ("5 minutes ago" or "in 5 minutes") and *durations* ("2 mins")!

 bundle should be configured and ready to go. If not, you
 can enable `Knp\Bundle\TimeBundle\KnpTimeBundle` manually.
 
-## USAGE
+## Usage
+
+### Twig
 
-In Twig:
+Time formatting:
 
 ```twig
-{{ someDateTimeVariable|ago }}
+{{ someDateTimeVariable|time_diff }} {# 2 weeks ago #}
 
-... or use the equivalent function:
-{{ time_diff(someDateTimeVariable) }}
+{# |ago is an alias for |time_diff #}
+{{ someDateTimeVariable|ago }} {# 1 second ago #}
+
+{# ... or use the equivalent function: #}
+{{ time_diff(someDateTimeVariable) }} {# in 2 months #}
 ```
 
-Note: the "ago" filter works fine for dates in the future, too. 
+> **Note**: the `time_diff` filter/function and `ago` alias works fine for dates in the future, too. 
 
-### In controllers
+Duration formatting:
 
-You can also "ago" dates inside PHP by autowiring the `Knp\Bundle\TimeBundle\DateTimeFormatter` service:
+```twig
+{{ someDurationInSeconds|duration }} {# 2 mins #}
+```
+
+### Service
+
+You can also format dates and durations in your services/controllers by autowiring/injecting the
+`Knp\Bundle\TimeBundle\DateTimeFormatter` service:
 
 ```
 use Knp\Bundle\TimeBundle\DateTimeFormatter;
 // ...
 
 public function yourAction(DateTimeFormatter $dateTimeFormatter)
 {
-    $someDate = new \DateTime('2017-02-11'); //or $entity->publishedDate()
-    $now = new \DateTime();
-    
-    $agoTime = $dateTimeFormatter->formatDiff($someDate, $now);
+    $someDate = new \DateTimeImmutable('2017-02-11'); // or $entity->publishedDate()
+    $toDate = new \DateTimeImmutable('now');
+
+    $agoTime = $dateTimeFormatter->formatDiff($someDate, $toDate); // $toDate parameter is optional and defaults to "now"
+
+    $readTime = $dateTimeFormatter->formatDuration(64); // or $entity->readTimeInSeconds()
+
     return $this->json([
-        ...
-        'published_at' => $agoTime
-        ...
+        //  ...
+        'published_at' => $agoTime, // 2 years ago
+        'read_time' => $readTime, // 1 min
+        // ...
     ]);
 }
 ```
 
 ## Controlling the Translation Locale
 
 The bundle will automatically use the current locale when translating
-the "ago" messages. However, you can override the locale:
+the "time_diff" ("ago") and "duration" messages. However, you can override
+the locale:
 
 ```twig
-{{ someDateTimeVariable|ago(locale='es') }}
+{{ someDateTimeVariable|time_diff(locale='es') }}
+
+{{ someDurationInSeconds|duration(locale='es') }}
 ```
