Installation is easy. Just plug Winston into your cable modem and then plug your existing router into Winston. You may have to reboot your router but none of your network settings will change.
After rebooting your router, navigate to http://winston.conf (note that this is an http page, not https) to confirm that everything's working. Your network will automatically be placed in Standard Privacy mode. While most tracking will be blocked we strongly recommend that you upgrade individual phones, tablets and computers to Ultra Privacy mode as this will strip out 99% of all tracking on those devices (even tracking which occurs in other applications and at the operating system level).
To start that process, select "Setup" on the main screen and follow the instructions in the Setup Wizard for your particular device.
