+A path is a series of keys separated by a dot.
+A key may contain special wildcard characters '\*' and '?'.
+To access an array value use the index as the key.
 To get the number of elements in an array or to access a child path, use the '#' character.
 The dot and wildcard characters can be escaped with '\'.

 ## Result Type
 
 GJSON supports the json types `string`, `number`, `bool`, and `null`. 
@@ -108,13 +110,44 @@ result.Type    // can be String, Number, True, False, Null, or JSON

+
+## Get nested array values
+
+Suppose you want all the last names from the following json:
+
+```json
+{
+  "programmers": [
+    {
+      "firstName": "Janet", 
+      "lastName": "McLaughlin", 
+    }, {
+      "firstName": "Elliotte",

+    }, {
+      "firstName": "Jason", 
+      "lastName": "Harold", 
+    }
+  ]
+}`
+```
+
+You would use the path "programmers.#.lastName" like such:
+
+```go
+result := gjson.Get(json, "programmers.#.lastName")
+for _,name := range result.Multi {
+	println(name.String())
+}
 ```
 
 ## Check for the existence of a value
 
 Sometimes you may want to see if the value actually existed in the json document.
 
-```
+```go
 value := gjson.Get(json, "name.last")
 if !value.Exists() {
 	println("no last name")
