Once downloaded, open terminal and go to the directory containing the binary. Execute following command:
First command copies the binary from current folder to system folder containing executable files.
Second command changes the permissions for the binary allowing to be executed by the user, group and others.
Third command executes (runs) the server. By default, it is running on the default loopback device, so it is inaccessible from the outer network.
Press CTRL + C in the command line to stop the server.
