To use ruby driver, you should have ruby 1.9.3 installed:

$ cd driver-ruby
$ rake install

To start the web API sender:

$ cd driver-ruby/websender
$ ruby server.rb

However, you should specify the configuration of web API sender beforehand:

:Port: 18188
:MimeTypes:
  html: text/html
  js: application/x-javascript
  css: text/css
:BA:
  :IP: 127.0.0.1
  :Port: 18181

18181 is the default port SF1R is listening at. If you want to send the API to the nginx reverse proxy, you should use a different configuration:

:Port: 18188
:MimeTypes:
  html: text/html
  js: application/x-javascript
  css: text/css
:NGINX_POSTFIX: sf1r
:BA:
  :IP: 127.0.0.1
  :Port: 8888

Here 8888 is the default port nginx is listening on.
