 Then `bundle install`.
 
 
 ## Basic usage
 
+Set both `ENV['AUTH_CLIENT_ID']` and `ENV['AUTH_CLIENT_SECRET']` somewhere (vhost configuration, heroku config, `config/environments/*` or even `config/application.rb`).
+
 ```ruby
 use OmniAuth::Builder do
   provider :exvo, ENV['AUTH_CLIENT_ID'], ENV['AUTH_CLIENT_SECRET']
 end
 ```
+
+If you'd like to use Exvo's staging auth, you need to pass the `:client_options` hash to override the default:
+
+```ruby
+use OmniAuth::Builder do
+  provider :exvo, ENV['AUTH_CLIENT_ID'], ENV['AUTH_CLIENT_SECRET'], :client_options => { :site => 'http://staging.auth.exvo.com' }
+end
+```
