+## Using custom transport
 
 The library uses Symfony HTTP Client and Guzzle as default transports.
 If those packages are not available then it falls back to the `file_get_contents`

 to HTTP client packages as may be the case when using PHP version prior to 8.0.
 
 In such cases it is suggested to use different transport. It can be achieved 
-by replacing the TransportFactory of the NbpClient with your own implementation.
