 ## PSR Log Route <span id="psr-log-route"></span>
 
+It is not necessary to `\yii1tech\psr\log\Logger` if you need to pass logs to PSR logger.
+As an alternative you can add `\yii1tech\psr\log\PsrLogRoute` log route to the standard Yii "log" component.

 ## Wrap Yii logger into PSR logger <span id="wrap-yii-logger-into-psr-logger"></span>
+
+There is another use case related to PSR logger besides bootstrapping eternal log storage.
+Sometimes 3rd party libraries may require PSR logger instance to be passed to them in order to function.
+For example, imagine we have a 3rd party library for "daemon" application running:
+
+```php
+<?php
+
+namespace vendor\daemon;
+
+use Psr\Log\LoggerInterface;
+
+class DaemonApplication
+{
+    public function __construct(LoggerInterface $logger)
+    {
+        // ....
+    }
+}
+```
+
+You can use `\yii1tech\psr\log\PsrLogger` to wrap standard Yii logging mechanism into PSR interface.
+
+Application configuration example:
+
+```php
+<?php
+
+return [
+    'components' => [
+        \Psr\Log\LoggerInterface::class => [
+            'class' => \yii1tech\psr\log\PsrLogger::class,
+        ],
+        // ...
+    ],
+    // ...
+];
+```
+
+Now while working with our example external "daemon" application, we can use following code:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+use vendor\daemon\DaemonApplication;
+
+$daemon = new DaemonApplication(Yii::app()->getComponent(LoggerInterface::class));
+// ...
+```
+
+> Note: in order to handle log context properly `\yii1tech\psr\log\PsrLogger` should be used in junction with `\yii1tech\psr\log\Logger`.
