-# mapstructure [![Godoc](https://godoc.org/github.com/mitchellh/mapstructure?status.svg)](https://godoc.org/github.com/mitchellh/mapstructure)
-
-mapstructure is a Go library for decoding generic map values to structures
-and vice versa, while providing helpful error handling.
-
-This library is most useful when decoding values from some data stream (JSON,
-Gob, etc.) where you don't _quite_ know the structure of the underlying data
-until you read a part of it. You can therefore read a `map[string]interface{}`
-and use this library to decode it into the proper underlying native Go
-structure.
-
-## Installation
-
-Standard `go get`:
-
-```
-$ go get github.com/mitchellh/mapstructure
-```
-
-## Usage & Example
-
-For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
-
-The `Decode` function has examples associated with it there.
-
-## But Why?!
-
-Go offers fantastic standard libraries for decoding formats such as JSON.
-The standard method is to have a struct pre-created, and populate that struct
-from the bytes of the encoded format. This is great, but the problem is if
-you have configuration or an encoding that changes slightly depending on
-specific fields. For example, consider this JSON:
-
-```json
-{
-  "type": "person",
-  "name": "Mitchell"
-}
-```
-
-Perhaps we can't populate a specific structure without first reading
-the "type" field from the JSON. We could always do two passes over the
-decoding of the JSON (reading the "type" first, and the rest later).
-However, it is much simpler to just decode this into a `map[string]interface{}`
-structure, read the "type" key, then use something like this library
-to decode it into the proper structure.
