Setup for Cuba in a sample app

I recently read up quite some articles on microframworks and I liked the idea to try out Cuba instead of the regular Sinatra for a change. Here is what I ended up with.

First of all my Gemfile:

source "https://rubygems.org"
ruby "2.0.0"

Since I did not want to constantly re-invent the wheel I will write down my choices for putting together my Cuba template.

1. Choose your favorite version of ruby and install it using rbenv (I happened to use MRI 2.2.3 at this point).
2. create your template directory and CD into it.
3. fix your ruby version using rbenv local 2.2.3 or somesuch
4. create a github repository and follow the instructions for the README.md and the first commit.
5. get a Gemfile from a running project and edit away the stuff I considered project specific
6. run bundle install, takes a while, but looks nice, remember to add Gemfile.lock to git too
7. create routes and config directories, want to put stuff in there
8. create an initial Cuba route in routes/default.rb

##Notes

• Follow 12 factor design (include the rails_12factor gem)
• Don't forget your Procfile with the command to start up your application server
• I prefer using external hosted logging services like Logentries (not in this guide)
• Set up performance monitoring AppSignal or New Relic (not in this guide)
