 ## Basic structure
 
 The basic structure of an rspec expectation is:
 
 ```ruby
-    expect(actual).to matcher(expected)
-    expect(actual).not_to matcher(expected)
+expect(actual).to matcher(expected)
+expect(actual).not_to matcher(expected)
 ```
 
 Note: You can also use `expect(..).to_not` instead of `expect(..).not_to`.

 ## What is a matcher?
 
 A matcher is any object that responds to the following methods:
 
 ```ruby
-    matches?(actual)
-    failure_message
+matches?(actual)
+failure_message
 ```
 
 These methods are also part of the matcher protocol, but are optional:
 
 ```ruby
-    does_not_match?(actual)
-    failure_message_when_negated
-    description
-    supports_block_expectations?
+does_not_match?(actual)

 RSpec ships with a number of built-in matchers and a DSL for writing custom
