+Perl Executing Browser - Logging
+--------------------------------------------------------------------------------
+
+PEB supports unified logging of Perl and JavaScript errors in the JavaScript console.  
+All you need to do to read error logs is to open the JavaScript console.  
+
+## Opening the JavaScript Console on QtWebkit Builds
+Start the QWebInspector using the keyboard shortcut <kbd>Ctrl</kbd> + <kbd>I</kbd> and go to the ``Console`` tab.  
+
+## Opening the JavaScript Console on QtWebEngine Builds
+Start PEB with the following command-line argument supplying an arbitrary private port:
+
+```bash
+peb --remote-debugging-port=8080
+```
+
+and open the following URL using any browser:
+
+``http://localhost:8080``
+
+to access the QtWebEngine Developer Tools and go to the ``Console`` tab.
