+//
+// 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) {
+//
+// 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"
+// )
+//
+// func TestSomething(t *testing.T) {
+// assert := assert.New(t)
+//
+// var a string = "Hello"
+// var b string = "Hello"
+//
+// assert.Equal(a, b, "The two words should be the same.")
+// }
+//
+// 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
+// testing framework. This allows the assertion funcs to write the failings and other details to
+// the correct place.
+//
+// Every assertion function also takes an optional string message as the final argument,
+// allowing custom error messages to be appended to the message the assertion method outputs.
