+<p align="center">set a json value quickly</p>
+
+SJSON is a Go package that provides a [very fast](#performance) and simple way to set a value in a json document.
+For quickly retrieving json values check out [GJSON](https://github.com/tidwall/gjson).
+
+For a command line interface check out [JJ](https://github.com/tidwall/jj).
+
+Getting Started
+===============
+
+Installing
+----------
+
+To start using SJSON, install Go and run `go get`:
+
+```sh
+$ go get -u github.com/tidwall/sjson
+```
+
+This will retrieve the library.
+
+Set a value
+-----------
+Set sets the value 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 validated. 
+Invalid json will not panic, but it may return back unexpected results.
+Invalid paths may return an error.
+
+```go
+package main
+
+import "github.com/tidwall/sjson"
+
+const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}`
+
+func main() {
+	value, _ := sjson.Set(json, "name.last", "Anderson")
+	println(value)
+}
+```
+
+This will print:
+
+```json
+{"name":{"first":"Janet","last":"Anderson"},"age":47}
+```
+
+Path syntax
+-----------
+
+A path is a series of keys separated by a dot.
+The dot and colon characters can be escaped with ``\``.
+
+```json
+{
+  "name": {"first": "Tom", "last": "Anderson"},
+  "age":37,
+  "children": ["Sara","Alex","Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+	{"first": "James", "last": "Murphy"},
+	{"first": "Roger", "last": "Craig"}
+  ]
+}
+```
+```
+"name.last"          >> "Anderson"
+"age"                >> 37
+"children.1"         >> "Alex"
+"friends.1.last"     >> "Craig"
+```
+
+The `-1` key can be used to append a value to an existing array:
+
+```
+"children.-1"  >> appends a new value to the end of the children array
+```
+
+Normally number keys are used to modify arrays, but it's possible to force a numeric object key by using the colon character:
+
+```json
+{
+  "users":{
+    "2313":{"name":"Sara"},
+    "7839":{"name":"Andy"}
+  }
+}
+```
+
+A colon path would look like:
+
+```
+"users.:2313.name"    >> "Sara"
+```
+
+Supported types
+---------------
+
+Pretty much any type is supported:
+
+```go
+sjson.Set(`{"key":true}`, "key", nil)
+sjson.Set(`{"key":true}`, "key", false)
+sjson.Set(`{"key":true}`, "key", 1)
+sjson.Set(`{"key":true}`, "key", 10.5)
+sjson.Set(`{"key":true}`, "key", "hello")
+sjson.Set(`{"key":true}`, "key", []string{"hello", "world"})
+sjson.Set(`{"key":true}`, "key", map[string]interface{}{"hello":"world"})
+```
+
+When a type is not recognized, SJSON will fallback to the `encoding/json` Marshaller.
+
+
+Examples
+--------
+
+Set a value from empty document:
+```go
+value, _ := sjson.Set("", "name", "Tom")
+println(value)
+
+// Output:
+// {"name":"Tom"}
+```
+
+Set a nested value from empty document:
+```go
+value, _ := sjson.Set("", "name.last", "Anderson")
+println(value)
+
+// Output:
+// {"name":{"last":"Anderson"}}
+```
+
+Set a new value:
+```go
+value, _ := sjson.Set(`{"name":{"last":"Anderson"}}`, "name.first", "Sara")
+println(value)
+
+// Output:
+// {"name":{"first":"Sara","last":"Anderson"}}
+```
+
+Update an existing value:
+```go
+value, _ := sjson.Set(`{"name":{"last":"Anderson"}}`, "name.last", "Smith")
+println(value)
+
+// Output:
+// {"name":{"last":"Smith"}}
+```
+
+Set a new array value:
+```go
+value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.2", "Sara")
+println(value)
+
+// Output:
+// {"friends":["Andy","Carol","Sara"]
+```
+
+Append an array value by using the `-1` key in a path:
+```go
+value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.-1", "Sara")
+println(value)
+
+// Output:
+// {"friends":["Andy","Carol","Sara"]
+```
+
+Append an array value that is past the end:
+```go
+value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.4", "Sara")
+println(value)
+
+// Output:
+// {"friends":["Andy","Carol",null,null,"Sara"]
+```
+
+Delete a value:
+```go
+value, _ := sjson.Delete(`{"name":{"first":"Sara","last":"Anderson"}}`, "name.first")
+println(value)
+
+// Output:
+// {"name":{"last":"Anderson"}}
+```
+
+Delete an array value:
+```go
+value, _ := sjson.Delete(`{"friends":["Andy","Carol"]}`, "friends.1")
+println(value)
+
+// Output:
+// {"friends":["Andy"]}
+```
+
+Delete the last array value:
+```go
+value, _ := sjson.Delete(`{"friends":["Andy","Carol"]}`, "friends.-1")
+println(value)
+
+// Output:
+// {"friends":["Andy"]}
+```

+
+Each operation was rotated though one of the following search paths:
+
+```
+widget.window.name
