gistfile1.txt

Create an account on heroku
Download your app from itp.nyu.edu
Cleanup config.ru
put everything in public

Install the heroku gem
- launch Terminal
- install heroku gem:
sudo gem install heroku
(type your computer's password)

Create the heroku project

- add you gems to the .gems file
- create a file called .gems in your project folder
- add these lines to it:
sinatra
dm-core
dm-yaml-adapter

plus any other gems you're using in your project

- make your config.ru file look like this:

require 'rubygems'
require 'sinatra'
require './app.rb'
run Sinatra::Application

- change all your urls to be the right thing, i.e. no itp.nyu.edu in them, etc.

- turn our project into a git repository
git init
git add .
git commit -am "initial commit"

heroku create <name-of-project>

git push heroku master
