+Package gorilla/schema fills a struct with form values.
+
+The basic usage is really simple. Given this struct:
+
+	type Person struct {
+		Name  string
+		Phone string
+	}
+
+...we can fill it passing a map to the Decode() function:
+
+	values := map[string][]string{
+		"Name":  {"John"},
+		"Phone": {"999-999-999"},
+	}
+	person := new(Person)
+	decoder := schema.NewDecoder()
+	decoder.Decode(person, values)
+
+This is just a simple example and it doesn't make a lot of sense to create
+the map manually. Typically it will come from a http.Request object and
+will be of type url.Values, http.Request.Form, or http.Request.MultipartForm:
+
+	func MyHandler(w http.ResponseWriter, r *http.Request) {
+		err := r.ParseForm()
+
+		if err != nil {
+			// Handle error
+		}
+
+		decoder := schema.NewDecoder()
+		// r.PostForm is a map of our POST form values
+		err := decoder.Decode(person, r.PostForm)
+
+		if err != nil {
+			// Handle error
+		}
+
+		// Do something with person.Name or person.Phone
+	}
+
+Note: it is a good idea to set a Decoder instance as a package global,
+because it caches meta-data about structs, and an instance can be shared safely:
+
+	var decoder = schema.NewDecoder()
+
+To define custom names for fields, use a struct tag "schema". To not populate
+certain fields, use a dash for the name and it will be ignored:
+
+	type Person struct {
+		Name  string `schema:"name"`  // custom name
+		Phone string `schema:"phone"` // custom name
+		Admin bool   `schema:"-"`     // this field is never set
+	}
+
+The supported field types in the destination struct are:
+
+  - bool
+  - float variants (float32, float64)
+  - int variants (int, int8, int16, int32, int64)
+  - string
+  - uint variants (uint, uint8, uint16, uint32, uint64)
+  - struct
+  - a pointer to one of the above types
+  - a slice or a pointer to a slice of one of the above types
+
+Non-supported types are simply ignored, however custom types can be registered
+to be converted.
+
+To fill nested structs, keys must use a dotted notation as the "path" for the
+field. So for example, to fill the struct Person below:
+
+	type Phone struct {
+		Label  string
+		Number string
+	}
+
+	type Person struct {
+		Name  string
+		Phone Phone
+	}
+
+...the source map must have the keys "Name", "Phone.Label" and "Phone.Number".
+This means that an HTML form to fill a Person struct must look like this:
+
+	<form>
+		<input type="text" name="Name">
+		<input type="text" name="Phone.Label">
+		<input type="text" name="Phone.Number">
+	</form>
+
+Single values are filled using the first value for a key from the source map.
+Slices are filled using all values for a key from the source map. So to fill
+a Person with multiple Phone values, like:
+
+	type Person struct {
+		Name   string
+		Phones []Phone
+	}
+
+...an HTML form that accepts three Phone values would look like this:
+
+	<form>
+		<input type="text" name="Name">
+		<input type="text" name="Phones.0.Label">
+		<input type="text" name="Phones.0.Number">
+		<input type="text" name="Phones.1.Label">
+		<input type="text" name="Phones.1.Number">
+		<input type="text" name="Phones.2.Label">
+		<input type="text" name="Phones.2.Number">
+	</form>
+
+Notice that only for slices of structs the slice index is required.
+This is needed for disambiguation: if the nested struct also had a slice
+field, we could not translate multiple values to it if we did not use an
+index for the parent struct.
+
+There's also the possibility to create a custom type that implements the
+TextUnmarshaler interface, and in this case there's no need to register
+a converter, like:
+
+	type Person struct {
+	  Emails []Email
+	}
+
+	type Email struct {
+	  *mail.Address
+	}
+
+	func (e *Email) UnmarshalText(text []byte) (err error) {
+		e.Address, err = mail.ParseAddress(string(text))
+		return
+	}
+
+...an HTML form that accepts three Email values would look like this:
+
+	<form>
+		<input type="email" name="Emails.0">
+		<input type="email" name="Emails.1">
+		<input type="email" name="Emails.2">
+	</form>
