+```ruby
+gem 'paypal-sdk-rest'
+```
 
 And then execute:
 
-    $ bundle
+```sh
+$ bundle
+```
 
 Or install it yourself as:
 
-    $ gem install paypal-sdk-rest
+```sh
+$ gem install paypal-sdk-rest
+```
 
 ## Configuration
 
 For Rails application:
 
-    rails g paypal:sdk:install
+```sh
+rails g paypal:sdk:install
+```
 
 For other ruby application, create a configuration file(`config/paypal.yml`):
 
-    development: &default
-      client_id: EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM
-      client_secret: EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM
-      mode: sandbox
-      # # with Proxy
-      # http_proxy: http://proxy-ipaddress:3129/
-      # # with CA File
-      # ssl_options:
-      #   ca_file: config/cacert.pem
-      # # Override Endpoint
-      # rest_endpoint: https://api.sandbox.paypal.com
-    test:
-      <<: *default
-    production:
-      <<: *default
-      mode: live
+```yaml
+development: &default
+  mode: sandbox
+  client_id: EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM
+  client_secret: EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM
+  # # with Proxy
+  # http_proxy: http://proxy-ipaddress:3129/
+  # # with CA File
+  # ssl_options:
+  #   ca_file: config/cacert.pem
+  # # Override Endpoint
+  # rest_endpoint: https://api.sandbox.paypal.com
+test:
+  <<: *default
+production:
+  mode: live
+  client_id: CLIENT_ID
+  client_secret: CLIENT_SECRET
+```
 
 
 Load Configurations from specified file:
 
-    PayPal::SDK::Core::Config.load('spec/config/paypal.yml',  ENV['RACK_ENV'] || 'development')
+```ruby
+PayPal::SDK::Core::Config.load('spec/config/paypal.yml',  ENV['RACK_ENV'] || 'development')
+```
 
 Without configuration file:
 
-    PayPal::SDK::REST.set_config(
-      :client_id => "EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM",
-      :client_secret => "EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM",
-      :mode => "sandbox", # "sandbox" or "live"
-      :ssl_options => { } )
+```ruby
+PayPal::SDK::REST.set_config(
+  :client_id => "EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM",
+  :client_secret => "EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM",
+  :mode => "sandbox", # "sandbox" or "live"
+  :ssl_options => { } )
+```
 
 Override configuration:
 
-    # Class level
-    Payment.set_config( :client_id => "123" )
+```ruby
+# Class level
+Payment.set_config( :client_id => "123" )
 
-    # Object level
-    payment.set_config( :client_id => "123" )
+# Object level
+payment.set_config( :client_id => "123" )
+```
