 |You can choose between two installation options:|::
 |             default and advanced.              |::
 |                                                |::
 | The advanced installation will install and run |::
 |  the masternode under a non-root user. If you  |::
 |  don't know what that means, use the default   |::
 |              installation method.              |::
 |                                                |::
 | Otherwise, your masternode will not work, and  |::
 |the Bulwark Team CANNOT assist you in repairing |::
 |        it. You will have to start over.        |::
 |                                                |::
 |Don't use the advanced option unless you are an |::
 |            experienced Linux user.             |::
 |                                                |::
