+# Short Variable Declaration
+
+Inside a function (even the main function), the `:=` short assignment statement can be used in place of a `var` declaration. The `:=` operator infers the type of the new variable based on the value.
+
+```go
+var empty string
+```
+
+Is the same as
+
+
+```go
+empty := ""
+```
+
+```go
+numCars := 10 // inferred to be an integer
+
+temperature := 0.0 // temperature is inferred to be a floating point value because it has a decimal point
+
+var isFunny = true // isFunny is inferred to be a boolean
+```
+
+Outside of a function (in the [global/package scope](https://dave.cheney.net/2017/06/11/go-without-package-scoped-variables)), every statement begins with a keyword (`var`, `func`, and so on) and so the `:=` construct is not available.
+
+## Assignment
+
+A lot of our users send birthday messages using the Textio API.
+
+Declare a variable named `congrats` with the value "happy birthday!" using a short variable declaration.
