+## Features
+
+- Primitives, arrays, maps, structs, time.Time and interface{}.
+- Appengine \*datastore.Key and datastore.Cursor.
+- [CustomEncoder]/[CustomDecoder] interfaces for custom encoding.
+- [Extensions](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-RegisterExt) to encode
+  type information.
+- Renaming fields via `msgpack:"my_field_name"` and alias via `msgpack:"alias:another_name"`.
+- Omitting individual empty fields via `msgpack:",omitempty"` tag or all
+  [empty fields in a struct](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-Marshal-OmitEmpty).
+- [Map keys sorting](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#Encoder.SetSortMapKeys).
+- Encoding/decoding all
+  [structs as arrays](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#Encoder.UseArrayEncodedStructs)
+  or
+  [individual structs](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-Marshal-AsArray).
+- [Encoder.SetCustomStructTag] with [Decoder.SetCustomStructTag] can turn msgpack into drop-in
+  replacement for any tag.
+- Simple but very fast and efficient
+  [queries](https://pkg.go.dev/github.com/vmihailenco/msgpack/v5#example-Decoder.Query).

+
+## Installation
+
+msgpack supports 2 last Go versions and requires support for
+[Go modules](https://github.com/golang/go/wiki/Modules). So make sure to initialize a Go module:
+
+```shell
+go mod init github.com/my/repo
+```
+
+And then install msgpack/v5 (note _v5_ in the import; omitting it is a popular mistake):
+
+```shell
+go get github.com/vmihailenco/msgpack/v5
+```
+
+## Quickstart
+
+```go
+import "github.com/vmihailenco/msgpack/v5"
+
+func ExampleMarshal() {
+    type Item struct {
+        Foo string
+    }
+
+    b, err := msgpack.Marshal(&Item{Foo: "bar"})
+    if err != nil {
+        panic(err)
+    }
+
+    var item Item
+    err = msgpack.Unmarshal(b, &item)
+    if err != nil {
+        panic(err)
+    }
+    fmt.Println(item.Foo)
+    // Output: bar
+}
+```
