Download the compiled binary and put it somewhere convenient for execution.
Execute the program, specifying the absolute path to the directory to use as a store for pastes using the --store argument. This must be an existing directory that is writeable by the user running gopaste. Gopaste will not attempt to create a directory itself.
The optional --port argument specifies the TCP port number on which to serve gopaste. The default value is 8000.
