A Rails app has a few top-level folders that serve different purposes.  This might vary from app to app, but most apps use this basic structure pretty faithfully.

app

This folder is where most of your code goes.  It has folders for your controllers (navigation logic), models (business logic), and views (display templates).  Sometimes developers create extra folders in here for objects like mailers and observers.  In Rails 3.1, an assets folder joined this group.  The assets folder contains files that get compiled into javascript code, stylesheets, and images.  These asset files are written in Ruby-like languages, but the rest of the code in the app folder is Ruby.

config

This folder has files that run when your app starts, including environment.rb and database.yml.  They control decisions about how the app works in different scenarios (examples: which email account should be used for outgoing messages? which database should be used for data stored by this server?).  The config folder also contains credent

These are the steps you will probably need to take, to get a new Rails app running.

1. install Rails

2. create a new Rails app

3. navigate into the root directory of your app

4. generate a scaffold
