Getting started with the Rails Girls App. Walk through of steps found at guides.railsgirls.com/app/
$ mkdir projects
Make a directory (folder) called “projects” This is just to keep all your code stuff together
$ cd projects
Change directory (open a diferent folder) to projects
$ rails new railsgirls
Use the “rails” program to create a new project called “railsgirls”. This is specific to rails. You cannot create a new word document with “$ word new awesome_paper”.
$ cd railsgirls
The pervious command (‘rails new railsgirls`) created a new directory (folder) called “railsgirls” - it ran the “mkdir railsgirls” all by itself! Change into (open) that folder to access the files there.
$ rails server
Start up the rails server.
You just started a server on your computer! A server SERVES up files to people who ask for them. Right now, our server is showing the “Welcome aboard” page when you go to localhost:3000/ - it’s “serving” that file up to you when you ask for it by going to that URL.
