$throttle->add(new Condition(60, 2)); // adds an interval where 2 increments are allowed in 60 seconds
$throttle->add(new Condition(600, 5)); // adds an interval where 5 increments are allowed in 10 minutes

// in each action you want to limit
try {
    $throttle->increment($_SERVER['REMOTE_ADDR']); // some client identifier like an ip or session id
    // NOTE: $_SERVER['REMOTE_ADDR'] may not gove you the actual client IP if you are behind a reverse proxy
