How I set up Travis CI

Here's travis' page on set up.

It's fine, except the .travis.yml example isn't very explicit. Here's ours:

rvm: '2.2.1'
script:
  - bundle exec bin/rake db:create
  - bundle exec bin/rake db:migrate
  - bundle exec rspec spec

The rvm's just our ruby version. You can set a bunch of different versions if you want to make sure your code is accessible to people on different ruby versions, but that's not really necessary when it's just the 5 of us working on it. Also, including pre v.2 ruby in here forces you to rewrite some phrases in old notation.

The next three lines are just standard for rails - just think of what you'd have to tell a new member of the team in setting up their machine to work on the project, which is what travis has to do.

If we were working on a js-heavy project with a lot of bower there'd be a lot of work to do here, but rails as always saves you trouble as long as you're doing something 'normal'.
