 ### Using the `Marshaler` and `encoding.TextUnmarshaler` interfaces

 ```toml

+contacts = [
+    "Donald Duck <donald@duckburg.com>",
+    "Scrooge McDuck <scrooge@duckburg.com>",
+]
 ```
 
-And you'll also need a `duration` type that satisfies the
-`encoding.TextUnmarshaler` interface:
+Can be decoded with:
 
 ```go
-type duration struct {
-	time.Duration
+// Create address type which satisfies the encoding.TextUnmarshaler interface.

+	*mail.Address
 }

+// Decode it.

+	blob := `
+		contacts = [
+			"Donald Duck <donald@duckburg.com>",
+			"Scrooge McDuck <scrooge@duckburg.com>",

+
+	var contacts struct {
+		Contacts []address
+	}
+
+	_, err := toml.Decode(blob, &contacts)
+	if err != nil {
+		log.Fatal(err)
+	}
+

+		fmt.Printf("%#v\n", c.Address)
+	}
+
+	// Output:
+	// &mail.Address{Name:"Donald Duck", Address:"donald@duckburg.com"}
+	// &mail.Address{Name:"Scrooge McDuck", Address:"scrooge@duckburg.com"}
+}
 ```
 
 To target TOML specifically you can implement `UnmarshalTOML` TOML interface in
 a similar way.
 
 ### More complex usage
-Here's an example of how to load the example from the official spec page:
-
-```toml
-# This is a TOML document. Boom.
-
-title = "TOML Example"
-
-[owner]
-name = "Tom Preston-Werner"
-organization = "GitHub"
-bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
-dob = 1979-05-27T07:32:00Z # First class dates? Why not?
-
-[database]
-server = "192.168.1.1"
-ports = [ 8001, 8001, 8002 ]
-connection_max = 5000
-enabled = true
-
-[servers]
-
-  # You can indent as you please. Tabs or spaces. TOML don't care.
-  [servers.alpha]
-  ip = "10.0.0.1"
-  dc = "eqdc10"
-
-  [servers.beta]
-  ip = "10.0.0.2"
-  dc = "eqdc10"
-
-[clients]
-data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
-
-# Line breaks are OK when inside arrays
-hosts = [
-  "alpha",
-  "omega"
-]
-```
-
-And the corresponding Go types are:
-
-```go
-type tomlConfig struct {
-	Title   string
-	Owner   ownerInfo
-	DB      database `toml:"database"`
-	Servers map[string]server
-	Clients clients
-}
-
-type ownerInfo struct {
-	Name string
-	Org  string `toml:"organization"`
-	Bio  string
-	DOB  time.Time
-}
-
-type database struct {
-	Server  string
-	Ports   []int
-	ConnMax int `toml:"connection_max"`
-	Enabled bool
-}
-
-type server struct {
-	IP string
-	DC string
-}
-
-type clients struct {
-	Data  [][]interface{}
-	Hosts []string
-}
-```
-
-Note that a case insensitive match will be tried if an exact match can't be
-found.
-
-A working example of the above can be found in `_example/example.{go,toml}`.
+See the [`_example/`](/_example) directory for a more complex example.
