    install Shotgun: gem install shotgun (this auto-reloads sinatra on every http request - which means every time you make a change in your code you don't have to stop then start sinatra)

    To just run your code using Sinatra: ruby name-of-file.rb
    To run your code using Shotgun (which is just Sinatra but with ability to auto-reload when changes are made to files): shotgun name-of-file.rb

    The following examples are run using Shotgun and the URL is: http://127.0.0.1:9393/

Setting Up Sinatra Flash

Sinatra Flash is an awesome gem that allows you to pop up little messages alerting your users of important things, via some simple code in your server.rb file. This is very useful for things like displaying error messages if the user has filled out a form wrong, or displaying "success" messages if the user did something successfully like sign in, sign out, or submit a form.

This also gives you a great chance to implement Foundation's beautiful alerts. Here's how to set it up!

1. Install the gem by typing gem install sinatra-flash in your terminal.
2. Require the gem in the top of your server.rb file: require 'sinatra/flash'
