+Interface mocking tool for go generate.
+
+By [Mat Ryer](https://twitter.com/matryer) and [David Hernandez](https://github.com/dahernan), with ideas lovingly stolen from [Ernesto Jimenez](https://github.com/ernesto-jimenez).
+
+### What is Moq?
+
+Moq is a tool that generates a struct from any interface. The struct can be used in test code as a mock of the interface.
+
+![Preview](preview.png)
+
+above: Moq generates the code on the right.
+
+You can read more in the [Meet Moq blog post](http://bit.ly/meetmoq).
+
+### Installing
+
+To start using Moq, just run go get:
+```
+$ go get github.com/matryer/moq
+```
+
+### Usage
+
+```
+moq [flags] destination interface [interface2 [interface3 [...]]]
+  -out string
+    	output file (default stdout)
+  -pkg string
+    	package name (default will infer)
+Specifying an alias for the mock is also supported with the format 'interface:alias'
+Ex: moq -pkg different . MyInterface:MyMock
+```
+
+In a command line:
+
+```
+$ moq -out mocks_test.go . MyInterface
+```
+
+In code (for go generate):
+
+```go
+package my
+
+//go:generate moq -out myinterface_moq_test.go . MyInterface
+
+type MyInterface interface {
+	Method1() error
+	Method2(i int)
+}
+```
+
+Then run `go generate` for your package.
+
+### How to use it
+
+Mocking interfaces is a nice way to write unit tests where you can easily control the behaviour of the mocked object.
+
+Moq creates a struct that has a function field for each method, which you can declare in your test code.
+
+In this example, Moq generated the `EmailSenderMock` type:
+
+```go
+func TestCompleteSignup(t *testing.T) {
+
+	var sentTo string
+
+	mockedEmailSender = &EmailSenderMock{
+		SendFunc: func(to, subject, body string) error {
+			sentTo = to
+			return nil
+		},
+	}
+
+	CompleteSignUp("me@email.com", mockedEmailSender)
+
+	callsToSend := len(mockedEmailSender.SendCalls())
+	if callsToSend != 1 {
+		t.Errorf("Send was called %d times", callsToSend)
+	}
+	if sentTo != "me@email.com" {
+		t.Errorf("unexpected recipient: %s", sentTo)
+	}
+
+}
+
+func CompleteSignUp(to string, sender EmailSender) {
+	// TODO: this
+}
+```
+
+The mocked structure implements the interface, where each method calls the associated function field.
+
+## Tips
+
+* Keep mocked logic inside the test that is using it
+* Only mock the fields you need
+* It will panic if a nil function gets called
+* Name arguments in the interface for a better experience
+* Use closured variables inside your test function to capture details about the calls to the methods
+* Use `.MethodCalls()` to track the calls
+* Use `go:generate` to invoke the `moq` command
