 ## Configure Generator
 
-Configure max attempts, base time, cap time and strategy. All options are not required. By default max attempts is `INF`, base time is 1 second, cap time is 1 minute, strategy is exponential with multiplier is 2.

-## Handle max attempts
-
-Set max attempts to zero or more and catch [MaxAttemptsException](../src/Generator/Exception/MaxAttemptsException.php) to take an action when max attempts has been over:
-
-```php
-<?php
-
-use Orangesoft\BackOff\Generator\GeneratorBuilder;
-use Orangesoft\BackOff\Generator\Exception\MaxAttemptsException;
-
-$generator = GeneratorBuilder::create()
-    ->setMaxAttempts(3)
-    ->build()
-;
-
-$attempt = 10;
-
-try {
-    $generator->generate($attempt);
-} catch (MaxAttemptsException $e) {
-    // ...
-}
-```
-
-Generator is independent of the generation sequence of the duration time.
-
 ## Use BackOff
 
 BackOff accepts Generator and Sleeper dependencies:
 
 ```php
 <?php
 
-use Orangesoft\BackOff\Generator\GeneratorBuilder;
+use Orangesoft\BackOff\Generator\Generator;
+use Orangesoft\BackOff\Duration\DurationInterface;
+use Orangesoft\BackOff\Duration\Milliseconds;
+use Orangesoft\BackOff\Strategy\ExponentialStrategy;
+use Orangesoft\BackOff\Jitter\NullJitter;
 use Orangesoft\BackOff\Sleeper\Sleeper;
 use Orangesoft\BackOff\BackOff;
 
-$generator = GeneratorBuilder::create()
-    ->setMaxAttempts(3)
-    ->build()
-;
-
-$sleeper = new Sleeper();
-
-$backOff = new BackOff($generator, $sleeper);
+$generator = new Generator(
+    baseTime: new Milliseconds(1_000),
+    capTime: new Milliseconds(60_000),
+    strategy: new ExponentialStrategy(multiplier: 2),
+    jitter: new NullJitter(),
+);
+
+$backOff = new BackOff(
+    maxAttempts: 3,
+    generator: $generator,
+    sleeper: new Sleeper(),
+);
 ```
 
 The main purpose of BackOff is to fall asleep for a while time or throw an exception if max attempts has been reached:
 
 ```php
-$backOff->backOff(10, new \RuntimeException());
+$backOff->backOff(4, new \RuntimeException());
 ```
 
-Use an exception that might be required to retry in your business logic.
-
-## Create BackOff facades
-
-Facades allow to quickly instance BackOff without using Generator. By default for [ExponentialBackOff](../src/Facade/ExponentialBackOff.php) max attempts is 5, base time is 1 second, cap time is 1 minute, multiplier is 2, Jitter is disabled and Sleeper is default:
+Use back-off decorators to quick instance. For example [ExponentialBackOff](../src/ExponentialBackOff.php) max attempts is 3, base time is 1 second, cap time is 1 minute, multiplier is 2, Jitter is disabled and Sleeper is default:

 use Orangesoft\BackOff\Sleeper\Sleeper;
 
-$maxAttempts = 3;
-$baseTimeMs = 1000;
-$capTimeMs = 60 * 1000;
-$multiplier = 2;
-$jitter = new DummyJitter();
-$sleeper = new Sleeper();
-
-$backOff = new ExponentialBackOff($maxAttempts, $baseTimeMs, $capTimeMs, $multiplier, $jitter, $sleeper);
+$backOff = new ExponentialBackOff(
+    maxAttempts: 3,
+    baseTime: new Milliseconds(1_000),
+    capTime: new Milliseconds(60_000),
+    multiplier: 2,
+    jitter: new NullJitter(),
+    sleeper: new Sleeper(),
