 Include the library with 'require':

+
+    require 'adwords_api'
 
 Then create an API instance:
-   adwords = AdwordsApi::Api.new
+
+    adwords = AdwordsApi::Api.new
 
 The created API object will grant you access to all the services for all of the
 currently supported vesions of the APIs. It uses a config file in:

+    ENV['HOME']/adwords_api.yml to read all of your configurations by default.
 
 There is an example configuration file shipped with these libraries.
 
 You can also pass API a manually constructed config hash like:
-   adwords = AdwordsApi::Api.new({
-     :authentication => {
-         :method => 'OAuth2',
-         :oauth2_client_id: 'INSERT_OAUTH2_CLIENT_ID_HERE'
-         :oauth2_client_secret: 'INSERT_OAUTH2_CLIENT_SECRET_HERE'
-         :developer_token => 'DEVELOPER_TOKEN',
-         :client_customer_id => '012-345-6789',
-         :user_agent => 'Ruby Sample'
-     },
-     :service => {
-       :environment => 'PRODUCTION'
-     }
-   })
-
-To obtain OAuth2 client credentials, follow instructions on the wiki:

 Once the library instance is create, specify which service you're looking to
 use, and which version:
-   campaign_srv = adwords.service(:CampaignService, :v201306)
 
-and you should now be able to just use the API methods in the object you were

 returned:
-   # Get 'Id', 'Name' and 'Status' fields of all campaigns.

+
+    # Get 'Id', 'Name' and 'Status' fields of all campaigns.
+    campaigns = campaign_srv.get({:fields => ['Id', 'Name', 'Status']})
 
 See the code in the examples directory for working examples you can build from.
 
 *Note*: if your setup requires you to send connections through a proxy server,
 please set the appropriate options in the config file or config hash. E.g.:
-   config[:connection] = {
-     :proxy => 'http://user:password@proxy_hostname:8080'
-   }
+
+    config[:connection] = {
+      :proxy => 'http://user:password@proxy_hostname:8080'
+    }
 
 *Note*: if you are using Ruby 1.8 you may need to include RubyGems to be able
 to require other gems code. There are several ways to do it, the easiest one is
 to pass '-rubygems' parameter to the ruby interpreter:
-   $ ruby -rubygems my_program_that_uses_gems
 
-you can also set this up in the environment:
-   $ export RUBYOPT="rubygems"
+    $ ruby -rubygems my_program_that_uses_gems
+
+You can also set this up in the environment:
+
+    $ export RUBYOPT="rubygems"
+
+Or add it to the bash configuration file:

-=== 2.1 - Ruby names for a Ruby library:
+### 2.1 - Ruby names for a Ruby library:
 
 In order to make things more Ruby-like for our Ruby developers, we've renamed
 API objects and methods to more closely match Ruby conventions. This means using
 snake_case for methods and parameters, and UpperCamelCase for class names.
 
-For example, the 'startDate' field of the Campaign object is named 'start_date'
-in the client library. The 'get' method, returns a CampaignPage object which has
-an 'entries' and a 'total_num_entries' field. So, to access the return
+For example, the `startDate` field of the Campaign object is named `start_date`
+in the client library. The `get` method, returns a CampaignPage object which has
+an `entries` and a `total_num_entries` field. So, to access the return
 values, you would do this:
 
-   response = campaign_srv.get(selector)
-   num_entries = response[:total_num_entries]
+    response = campaign_srv.get(selector)
+    num_entries = response[:total_num_entries]
 
 Essentially, all you have to do is follow Ruby conventions, and the library will
 do the rest. All of the examples are written following this standard.

-=== 2.3 - Logging:
+### 2.3 - Logging:
 
 It is often useful to see a trace of the raw SOAP XML being sent and received.
 The quickest way of achieving this when debugging your application is by setting
 the library.log_level configuration variable to 'DEBUG':
-   config[:library] = {
-     :log_level => 'DEBUG'
-   }
+
+    config[:library] = {
+      :log_level => 'DEBUG'
+    }
+
 or via configuration file (see example).
 
 This will output the SOAP XML to stderr, which will usually show up in your
@@ -135,89 +148,92 @@ terminal window.
 
 There's also an option of logging requests and XML to a file. In order to enable
 this, you should create a standard Logger object and pass it to the library:
-   require 'logger'
-   logger = Logger.new('path/to/log_filename')
-   logger.level = Logger::DEBUG
-   adwords = AdwordsApi::Api.new
-   adwords.logger = logger
+
+    require 'logger'
+    logger = Logger.new('path/to/log_filename')
+    logger.level = Logger::DEBUG
+    adwords = AdwordsApi::Api.new
+    adwords.logger = logger
 
 Request details and units spend are logged at the INFO log level, while raw HTTP
 headers and XML dumps are logged at the DEBUG log level. For more details on
 using Logger refer to the Ruby Logger documentation.
 
-=== 2.4 - Calculating operations usage
+### 2.4 - Calculating operations usage
 
 Each AdWords API operation performed consumes a certain number of operations as
-described in the rate sheet:
-
-  https://developers.google.com/adwords/api/docs/ratesheet
+described in the
+[rate sheet](https://developers.google.com/adwords/api/docs/ratesheet).
 
 The amount of operations consumed is returned in the header part of the SOAP
 response. This information can be obtained by passing a user block during the
 method call:
 
-  response = campaign_srv.get(selector) do |header|
-    puts "Operations consumed: %d" % header[:operations]
-  end
+    response = campaign_srv.get(selector) do |header|
+      puts "Operations consumed: %d" % header[:operations]
+    end
 
 You can also retrieve the response body as the second block parameter:
-  campaign_srv.get(selector) {|header, body| ... }
 
-=== 2.5 - GZip compression
+    campaign_srv.get(selector) {|header, body| ... }
+
+### 2.5 - GZip compression
 
 The library offers a transparent compression option which can be enabled in the
 configuration file or by the following setting:
 
-   config[:connection] = {
-     :enable_gzip => true
-   }
+    config[:connection] = {
+      :enable_gzip => true
+    }
 
 Enabling this option will set the headers required to request the server to
 respond in gzipped format. All requests are sent uncompressed regardless.
