 you'll have no problem to set this up. For inspiration, look at the
 [foodcoops.net production setup](https://github.com/foodcoops/foodcoops.net).
 
-
-## Capistrano
-
-### Setup
-
-1. Initialise your [Capistrano](http://capistranorb.com/) setup
-
-        bundle exec cap install
-        sed -i 's|^# \(require.*rails.*\)|\1|' Capfile
-        cp config/deploy.rb.SAMPLE config/deploy.rb
-
-   When you're using [RVM](http://rvm.io/) on the server you may want to
-   uncomment the corresponding line in `Capfile`.
-
-2. Adapt your configuration in `config/deploy.rb` and `config/deploy/*.rb`
-
-
-### Deploy
-
-On your first deploy you should run (choose either staging or production)
-
-    bundle exec cap staging deploy:check
-
-This will fail, which is ok, because there is no configuration yet. On your
-server, there is a directory `shared/config` for each installation, which
-contains the configuration. Create `database.yml`, `app_config.yml` and
-`initializers/secret_token.rb` and try again.
-(See `lib/capistrano/tasks/deploy_initial.cap` for a way to automate this.)

-Deploy to staging
-
-    bundle exec cap staging deploy
-
-Deploy to production

-    bundle exec cap production deploy
