+<p align="center">get a json value quickly</a></p>
+
+GJSON is a Go package that provides a [very fast](#performance) and simple way to get a value from a json document. The purpose for this library it to give efficient json indexing for the [BuntDB](https://github.com/tidwall/buntdb) project. 
+
+Getting Started
+===============
+
+## Installing
+
+To start using GJSON, install Go and run `go get`:
+
+```sh
+$ go get -u github.com/tidwall/gjson
+```
+
+This will retrieve the library.
+
+## Get a value
+Get searches json for the specified path. A path is in dot syntax, such as "name.last" or "age". This function expects that the json is well-formed and validates. Invalid json will not panic, but it may return back unexpected results. When the value is found it's returned immediately. 
+
+```go
+package main
+
+import "github.com/tidwall/gjson"
+
+const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}`
+
+func main() {
+	value := gjson.Get(json, "name.last")
+	println(value.String())
+}
+```
+
+This will print:
+
+```
+Prichard
+```
+*There's also the [GetMany](#get-multiple-values-at-once) function to get multiple values at once, and [GetBytes](#working-with-bytes) for working with JSON byte slices.*
+
+## Path Syntax
+
+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 '\'.
+
+```json
+{
+  "name": {"first": "Tom", "last": "Anderson"},
+  "age":37,
+  "children": ["Sara","Alex","Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+    {"first": "Dale", "last": "Murphy", "age": 44},
+    {"first": "Roger", "last": "Craig", "age": 68},
+    {"first": "Jane", "last": "Murphy", "age": 47}
+  ]
+}
+```
+```
+"name.last"          >> "Anderson"
+"age"                >> 37
+"children"           >> ["Sara","Alex","Jack"]
+"children.#"         >> 3
+"children.1"         >> "Alex"
+"child*.2"           >> "Jack"
+"c?ildren.0"         >> "Sara"
+"fav\.movie"         >> "Deer Hunter"
+"friends.#.first"    >> ["Dale","Roger","Jane"]
+"friends.1.last"     >> "Craig"
+```
+
+You can also query an array for the first match by using `#[...]`, or find all matches with `#[...]#`. 
+Queries support the `==`, `!=`, `<`, `<=`, `>`, `>=` comparison operators and the simple pattern matching `%` operator.
+
+```
+friends.#[last=="Murphy"].first    >> "Dale"
+friends.#[last=="Murphy"]#.first   >> ["Dale","Jane"]
+friends.#[age>45]#.last            >> ["Craig","Murphy"]
+friends.#[first%"D*"].last         >> "Murphy"
+```
+
+## Result Type
+
+GJSON supports the json types `string`, `number`, `bool`, and `null`. 
+Arrays and Objects are returned as their raw json types. 
+
+The `Result` type holds one of these:
+
+```
+bool, for JSON booleans
+float64, for JSON numbers
+string, for JSON string literals
+nil, for JSON null
+```
+
+To directly access the value:
+
+```go
+result.Type    // can be String, Number, True, False, Null, or JSON
+result.Str     // holds the string
+result.Num     // holds the float64 number
+result.Raw     // holds the raw json
+result.Index   // index of raw value in original json, zero means index unknown
+```
+
+There are a variety of handy functions that work on a result:
+
+```go
+result.Value() interface{}
+result.Int() int64
+result.Uint() uint64
+result.Float() float64
+result.String() string
+result.Bool() bool
+result.Array() []gjson.Result
+result.Map() map[string]gjson.Result
+result.Get(path string) Result
+result.ForEach(iterator func(key, value Result) bool)
+result.Less(token Result, caseSensitive bool) bool
+```
+
+The `result.Value()` function returns an `interface{}` which requires type assertion and is one of the following Go types:
+
+
+
+The `result.Array()` function returns back an array of values.
+If the result represents a non-existent value, then an empty array will be returned.
+If the result is not a JSON array, the return value will be an array containing one result.
+
+```go
+boolean >> bool
+number  >> float64
+string  >> string
+null    >> nil
+array   >> []interface{}
+object  >> map[string]interface{}
+```
+
+## Get nested array values
+
+Suppose you want all the last names from the following json:
+
+```json
+{
+  "programmers": [
+    {
+      "firstName": "Janet", 
+      "lastName": "McLaughlin", 
+    }, {
+      "firstName": "Elliotte", 
+      "lastName": "Hunter", 
+    }, {
+      "firstName": "Jason", 
+      "lastName": "Harold", 
+    }
+  ]
+}`
+```
+
+You would use the path "programmers.#.lastName" like such:
+
+```go
+result := gjson.Get(json, "programmers.#.lastName")
+for _,name := range result.Array() {
+	println(name.String())
+}
+```
+
+You can also query an object inside an array:
+
+```go
+name := gjson.Get(json, `programmers.#[lastName="Hunter"].firstName`)
+println(name.String())  // prints "Elliotte"
+```
+
+## Iterate through an object or array
+
+The `ForEach` function allows for quickly iterating through an object or array. 
+The key and value are passed to the iterator function for objects.
+Only the value is passed for arrays.
+Returning `false` from an iterator will stop iteration.
+
+```go
+result := gjson.Get(json, "programmers")
+result.ForEach(func(key, value gjson.Result) bool{
+	println(value.String()) 
+	return true // keep iterating
+})
+```
+
+## Simple Parse and Get
+
+There's a `Parse(json)` function that will do a simple parse, and `result.Get(path)` that will search a result.
+
+For example, all of these will return the same result:
+
+```go
+gjson.Parse(json).Get("name").Get("last")
+gjson.Get(json, "name").Get("last")
+gjson.Get(json, "name.last")
+```
+
+## Check for the existence of a value
+
+Sometimes you just want to know if a value exists. 
+
+```go
+value := gjson.Get(json, "name.last")
+if !value.Exists() {
+	println("no last name")
+} else {
+	println(value.String())
+}
+
+// Or as one step
+if gjson.Get(json, "name.last").Exists(){
+	println("has a last name")
+}
+```
+
+## Unmarshal to a map
+
+To unmarshal to a `map[string]interface{}`:
+
+```go
+m, ok := gjson.Parse(json).Value().(map[string]interface{})
+if !ok{
+	// not a map
+}
+```
+
+## Working with Bytes
+
+If your JSON is contained in a `[]byte` slice, there's the [GetBytes](https://godoc.org/github.com/tidwall/gjson#GetBytes) function. This is preferred over `Get(string(data), path)`.
+
+```go
+var json []byte = ...
+result := gjson.GetBytes(json, path)
+```
+
+If you are using the `gjson.GetBytes(json, path)` function and you want to avoid converting `result.Raw` to a `[]byte`, then you can use this pattern:
+
+```go
+var json []byte = ...
+result := gjson.GetBytes(json, path)
+var raw []byte
+if result.Index > 0 {
+    raw = json[result.Index:result.Index+len(result.Raw)]
+} else {
+    raw = []byte(result.Raw)
+}
+```
+
+This is a best-effort no allocation sub slice of the original json. This method utilizes the `result.Index` field, which is the position of the raw data in the original json. It's possible that the value of `result.Index` equals zero, in which case the `result.Raw` is converted to a `[]byte`.
+
+## Get multiple values at once
+
+The `GetMany` function can be used to get multiple values at the same time, and is optimized to scan over a JSON payload once.
+
+```go
+results := gjson.GetMany(json, "name.first", "name.last", "age")
+```
+
+The return value is a `[]Result`, which will always contain exactly the same number of items as the input paths.

+Each operation was rotated though one of the following search paths:
+
+```
+widget.window.name
+widget.image.hOffset
+widget.text.onMouseUp
+```
+
+For the `GetMany` benchmarks these paths are used:
+
+```
+widget.window.name
+widget.image.hOffset
+widget.text.onMouseUp
+widget.window.title
+widget.image.alignment
+widget.text.style
+widget.window.height
+widget.image.src
+widget.text.data
+widget.text.size
+```
