Installing Ruby
---------------
	The first step is to install some dependencies for Ruby.

		sudo apt-get update
		sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

	Next we're going to be installing Ruby using one of three methods. Each have their own benefits, most people prefer using rbenv these days, but if you're familiar with rvm you can follow those steps as well. I've included instructions for installing from source as well, but in general, you'll want to choose either rbenv or rvm.

	Choose one method. Some of these conflict with each other, so choose the one that sounds the most interesting to you, or go with my suggestion, rbenv.

	Installing with rbenv is a simple two step process. First you install rbenv, and then ruby-build:

		cd
		git clone git://github.com/sstephenson/rbenv.git .rbenv
		echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
		echo 'eval "$(rbenv init -)"' >> ~/.bashrc
		exec $SHELL

		git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
		echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
		exec $SHELL

		git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~/.rbenv/plugins/rbenv-gem-rehash

		rbenv install 2.2.1
		rbenv global 2.2.1
		ruby -v

	Now we tell Rubygems not to install the documentation for each package locally and then install Bundler

		echo "gem: --no-ri --no-rdoc" > ~/.gemrc
		gem install bundler


Configuring Git
---------------

	We'll be using Git for our version control system so we're going to set it up to match our Github account. If you don't already have a Github account, make sure to register. It will come in handy for the future.

	Replace my name and email address in the following steps with the ones you used for your Github account.

		git config --global color.ui true
		git config --global user.name "YOUR NAME"
		git config --global user.email "[email protected]"
		ssh-keygen -t rsa -C "[email protected]"

	The next step is to take the newly generated SSH key and add it to your Github account. You want to copy and paste the output of the following command and paste it here.

		cat ~/.ssh/id_rsa.pub

	Once you've done this, you can check and see if it worked:

		ssh -T [email protected]

	You should get a message like this:

		Hi excid3! You've successfully authenticated, but GitHub does not provide shell access.


Installing Rails
----------------
	Since Rails ships with so many dependencies these days, we're going to need to install a Javascript runtime like NodeJS. This lets you use Coffeescript and the Asset Pipeline in Rails which combines and minifies your javascript to provide a faster production environment.

	To install NodeJS, we're going to add it using a PPA repository:

		sudo add-apt-repository ppa:chris-lea/node.js
		sudo apt-get update
		sudo apt-get install nodejs

	And now, without further adieu:

		gem install rails -v 4.2.0
	
	If you're using rbenv, you'll need to run the following command to make the rails executable available:

		rbenv rehash
	
	Now that you've installed Rails, you can run the rails -v command to make sure you have everything installed correctly:

		rails -v
		# Rails 4.2.0

	If you get a different result for some reason, it means your environment may not be setup properly.


Setting Up PostgreSQL
---------------------
	For PostgreSQL, we're going to add a new repository to easily install a recent version of Postgres 9.3.

		sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
		wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -
		sudo apt-get update
		sudo apt-get install postgresql-common
		sudo apt-get install postgresql-9.3 libpq-dev

	The postgres installation doesn't setup a user for you, so you'll need to follow these steps to create a user with permission to create databases. Feel free to replace chris with your username.

		sudo -u postgres createuser chris -s

		# If you would like to set a password for the user, you can do the following
		sudo -u postgres psql
		postgres=# \password chris


Final Steps
-----------
	And now for the moment of truth. Let's create your first Rails application:

		#### If you want to use SQLite (not recommended)
		rails new myapp

		#### If you want to use MySQL
		rails new myapp -d mysql

		#### If you want to use Postgres
		# Note that this will expect a postgres user with the same username
		# as your app, you may need to edit config/database.yml to match the
		# user you created earlier
		rails new myapp -d postgresql

		# Move into the application directory
		cd myapp

		# If you setup MySQL or Postgres with a username/password, modify the
		# config/database.yml file to contain the username/password that you specified

		# Create the database
		rake db:create

		rails server

	You can now visit http://localhost:3000 to view your new website!

	Now that you've got your machine setup, it's time to start building some Rails applications.

	If you received an error that said Access denied for user 'root'@'localhost' (using password: NO) then you need to update your config/database.yml file to match the database username and password.


Install AMPL and Bonmin
-----------------------
	You can find the ampl and bonmin binaries in the inside the bin folder, which is located in the root folder of vagato rails app.

	To install these binaries, on an Ubuntu Linux computer, just copy them into your /bin folder.
