+   The ``local/bin/php`` is used to run deployer binary at remote. The value for ``local/bin/php`` is
+   auto detected, based on ``composer.json``, but if you have non standard php binary location you can set it manually.
+   It should have the same value as ``bin/php`. If you want ``bin/php`` to be also auto detected then you need to
+   install https://github.com/sourcebroker/deployer-extended and add ``'path' => 'vendor/sourcebroker/deployer-extended/includes/settings/bin_php.php'``
+   to loader from point 2. Then for standard hosting config you do not need to set either `bin/php` or `local/bin/php`.

 6) Add "db_databases" var for all other hosts. For example for live host it can be:
    ::
 
       host('live')
           ->setHostname('my-server.example.com')
           ->setRemoteUser('deploy')
