Ruby Installation Error

So I've been working on setting up Ruby for my Windows computer, more particularly Windows 8.1. I've made it through every step, except when I type in localhost:3000 into my internet browser, Firefox says:

Unable to connect

Firefox can't establish a connection to the server at localhost:3000.

Does anyone know what could be my problem? Everything I installed in CMD seemed to work properly, although at times it would say "DL is deprecated, please use Fiddle", then pause for a second. After this, it just finishes the operation.

You have to start the rails server before you can connect to it via the browser. First you need to create a new rails application.

rails new testapp

Then you need to enter the testapp folder and start the rails server from the bin directory.

cd testapp

bin/rails server

Then you should be able to access the the server at localhost:3000
