 // Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
 //
-// Example Usage
+// # Example Usage
 //
 // The following is a complete example using assert in a standard test function:
-//    import (
-//      "testing"
-//      "github.com/stretchr/testify/assert"
-//    )
 //
-//    func TestSomething(t *testing.T) {
+//	import (
+//	  "testing"
+//	  "github.com/stretchr/testify/assert"
+//	)
 //
-//      var a string = "Hello"
-//      var b string = "Hello"
+//	func TestSomething(t *testing.T) {
 //
-//      assert.Equal(t, a, b, "The two words should be the same.")
+//	  var a string = "Hello"
+//	  var b string = "Hello"
 //
-//    }
+//	  assert.Equal(t, a, b, "The two words should be the same.")
+//
+//	}
 //
 // if you assert many times, use the format below:
 //
-//    import (
-//      "testing"
-//      "github.com/stretchr/testify/assert"
-//    )
+//	import (
+//	  "testing"
+//	  "github.com/stretchr/testify/assert"
+//	)
 //
-//    func TestSomething(t *testing.T) {
-//      assert := assert.New(t)
+//	func TestSomething(t *testing.T) {
+//	  assert := assert.New(t)
 //
-//      var a string = "Hello"
-//      var b string = "Hello"
+//	  var a string = "Hello"
+//	  var b string = "Hello"
 //
-//      assert.Equal(a, b, "The two words should be the same.")
-//    }
+//	  assert.Equal(a, b, "The two words should be the same.")
+//	}
 //
-// Assertions
+// # Assertions
 //
 // Assertions allow you to easily write test code, and are global funcs in the `assert` package.
 // All assertion functions take, as the first argument, the `*testing.T` object provided by the
