+![Gabs](gabs_logo.png "Gabs")
+
+Gabs is a small utility for dealing with dynamic or unknown JSON structures in
+golang. It's pretty much just a helpful wrapper around the golang
+`json.Marshal/json.Unmarshal` behaviour and `map[string]interface{}` objects.
+It does nothing spectacular except for being fabulous.
+
+https://godoc.org/github.com/Jeffail/gabs
+
+## How to install:
+
+``` bash
+go get github.com/Jeffail/gabs
+```
+
+## How to use
+
+### Parsing and searching JSON
+
+``` go
+...
+
+import "github.com/Jeffail/gabs"
+
+jsonParsed, err := gabs.ParseJSON([]byte(`{
+	"outter":{
+		"inner":{
+			"value1":10,
+			"value2":22
+		},
+		"alsoInner":{
+			"value1":20
+		}
+	}
+}`))
+
+var value float64
+var ok bool
+
+value, ok = jsonParsed.Path("outter.inner.value1").Data().(float64)
+// value == 10.0, ok == true
+
+value, ok = jsonParsed.Search("outter", "inner", "value1").Data().(float64)
+// value == 10.0, ok == true
+
+value, ok = jsonParsed.Path("does.not.exist").Data().(float64)
+// value == 0.0, ok == false
+
+exists := jsonParsed.Exists("outter", "inner", "value1")
+// exists == true
+
+exists := jsonParsed.Exists("does", "not", "exist")
+// exists == false
+
+exists := jsonParsed.ExistsP("does.not.exist")
+// exists == false
+
+...
+```
+
+### Iterating objects
+
+``` go
+...
+
+jsonParsed, _ := gabs.ParseJSON([]byte(`{"object":{ "first": 1, "second": 2, "third": 3 }}`))
+
+// S is shorthand for Search
+children, _ := jsonParsed.S("object").ChildrenMap()
+for key, child := range children {
+	fmt.Printf("key: %v, value: %v\n", key, child.Data().(string))
+}
+
+...
+```
+
+### Iterating arrays
+
+``` go
+...
+
+jsonParsed, _ := gabs.ParseJSON([]byte(`{"array":[ "first", "second", "third" ]}`))
+
+// S is shorthand for Search
+children, _ := jsonParsed.S("array").Children()
+for _, child := range children {
+	fmt.Println(child.Data().(string))
+}
+
+...
+```
+
+Will print:
+
+```
+first
+second
+third
+```
+
+Children() will return all children of an array in order. This also works on
+objects, however, the children will be returned in a random order.
+
+### Searching through arrays
+
+If your JSON structure contains arrays you can still search the fields of the
+objects within the array, this returns a JSON array containing the results for
+each element.
+
+``` go
+...
+
+jsonParsed, _ := gabs.ParseJSON([]byte(`{"array":[ {"value":1}, {"value":2}, {"value":3} ]}`))
+fmt.Println(jsonParsed.Path("array.value").String())
+
+...
+```
+
+Will print:
+
+```
+[1,2,3]
+```
+
+### Generating JSON
+
+``` go
+...
+
+jsonObj := gabs.New()
+// or gabs.Consume(jsonObject) to work on an existing map[string]interface{}
+
+jsonObj.Set(10, "outter", "inner", "value")
+jsonObj.SetP(20, "outter.inner.value2")
+jsonObj.Set(30, "outter", "inner2", "value3")
+
+fmt.Println(jsonObj.String())
+
+...
+```
+
+Will print:
+
+```
+{"outter":{"inner":{"value":10,"value2":20},"inner2":{"value3":30}}}
+```
+
+To pretty-print:
+
+``` go
+...
+
+fmt.Println(jsonObj.StringIndent("", "  "))
+
+...
+```
+
+Will print:
+
+```
+{
+  "outter": {
+    "inner": {
+      "value": 10,
+      "value2": 20
+    },
+    "inner2": {
+      "value3": 30
+    }
+  }
+}
+```
+
+### Generating Arrays
+
+``` go
+...
+
+jsonObj := gabs.New()
+
+jsonObj.Array("foo", "array")
+// Or .ArrayP("foo.array")
+
+jsonObj.ArrayAppend(10, "foo", "array")
+jsonObj.ArrayAppend(20, "foo", "array")
+jsonObj.ArrayAppend(30, "foo", "array")
+
+fmt.Println(jsonObj.String())
+
+...
+```
+
+Will print:
+
+```
+{"foo":{"array":[10,20,30]}}
+```
+
+Working with arrays by index:
+
+``` go
+...
+
+jsonObj := gabs.New()
+
+// Create an array with the length of 3
+jsonObj.ArrayOfSize(3, "foo")
+
+jsonObj.S("foo").SetIndex("test1", 0)
+jsonObj.S("foo").SetIndex("test2", 1)
+
+// Create an embedded array with the length of 3
+jsonObj.S("foo").ArrayOfSizeI(3, 2)
+
+jsonObj.S("foo").Index(2).SetIndex(1, 0)
+jsonObj.S("foo").Index(2).SetIndex(2, 1)
+jsonObj.S("foo").Index(2).SetIndex(3, 2)
+
+fmt.Println(jsonObj.String())
+
+...
+```
+
+Will print:
+
+```
+{"foo":["test1","test2",[1,2,3]]}
+```
+
+### Converting back to JSON
+
+This is the easiest part:
+
+``` go
+...
+
+jsonParsedObj, _ := gabs.ParseJSON([]byte(`{
+	"outter":{
+		"values":{
+			"first":10,
+			"second":11
+		}
+	},
+	"outter2":"hello world"
+}`))
+
+jsonOutput := jsonParsedObj.String()
+// Becomes `{"outter":{"values":{"first":10,"second":11}},"outter2":"hello world"}`
+
+...
+```
+
+And to serialize a specific segment is as simple as:
+
+``` go
+...
+
+jsonParsedObj := gabs.ParseJSON([]byte(`{
+	"outter":{
+		"values":{
+			"first":10,
+			"second":11
+		}
+	},
+	"outter2":"hello world"
+}`))
+
+jsonOutput := jsonParsedObj.Search("outter").String()
+// Becomes `{"values":{"first":10,"second":11}}`
+
+...
+```
+
+### Merge two containers
+
+You can merge a JSON structure into an existing one, where collisions will be
+converted into a JSON array.
+
+``` go
+jsonParsed1, _ := ParseJSON([]byte(`{"outter": {"value1": "one"}}`))
+jsonParsed2, _ := ParseJSON([]byte(`{"outter": {"inner": {"value3": "three"}}, "outter2": {"value2": "two"}}`))
+
+jsonParsed1.Merge(jsonParsed2)
+// Becomes `{"outter":{"inner":{"value3":"three"},"value1":"one"},"outter2":{"value2":"two"}}`
+```
+
+Arrays are merged:
+
+``` go
+jsonParsed1, _ := ParseJSON([]byte(`{"array": ["one"]}`))
+jsonParsed2, _ := ParseJSON([]byte(`{"array": ["two"]}`))
+
+jsonParsed1.Merge(jsonParsed2)
+// Becomes `{"array":["one", "two"]}`
+```
+
+### Parsing Numbers
+
+Gabs uses the `json` package under the bonnet, which by default will parse all
+number values into `float64`. If you need to parse `Int` values then you should
+use a `json.Decoder` (https://golang.org/pkg/encoding/json/#Decoder):
+
+``` go
+sample := []byte(`{"test":{"int":10, "float":6.66}}`)
+dec := json.NewDecoder(bytes.NewReader(sample))
+dec.UseNumber()
+
+val, err := gabs.ParseJSONDecoder(dec)
+if err != nil {
+    t.Errorf("Failed to parse: %v", err)
+    return
+}
+
+intValue, err := val.Path("test.int").Data().(json.Number).Int64()
+```

 ## Updating go-steam to a new SteamKit version
 
-To update go-steam to a new version of SteamKit, do the following:
+Go source code is generated with code in the `generator` directory.
+Look at `generator/README.md` for more information on how to use the generator.
 
-	go get github.com/golang/protobuf/protoc-gen-go/
+Then, after generating new Go source files, update `go-steam` as necessary.
-    git submodule init && git submodule update
-    cd generator
-    go run generator.go clean proto steamlang
-
-Make sure that `$GOPATH/bin` / `protoc-gen-go` is in your `$PATH`. You'll also need [`protoc`](https://developers.google.com/protocol-buffers/docs/downloads), the protocol buffer compiler. At the moment, we use Protocol Buffers 2.6.1 with `proco-gen-go`-[2402d76](https://github.com/golang/protobuf/tree/2402d76f3d41f928c7902a765dfc872356dd3aad).
-
-To compile the Steam Language files, you also need the [.NET Framework](https://www.microsoft.com/net/downloads)
-on Windows or [mono](http://www.go-mono.com/mono-downloads/download.html) on other operating systems.
-
-Apply the protocol changes where necessary.
