Now that we have successfully started the Selenium Grid hub, we will need to have a look at how we can start adding Selenium servers to the hub so that it starts forming the grid of computers that we are expecting. You will notice that compared to Selenium Grid for Selenium 1, we won't have to add a new server for each browser that we want to use.
