+# 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.

+
+Easy and safe casting from one type to another in Go
+
+Don’t Panic! ... Cast
+
+## What is Cast?
+
+Cast is a library to convert between different go types in a consistent and easy way.
+
+Cast provides simple functions to easily convert a number to a string, an
+interface into a bool, etc. Cast does this intelligently when an obvious
+conversion is possible. It doesn’t make any attempts to guess what you meant,
+for example you can only convert a string to an int when it is a string
+representation of an int such as “8”. Cast was developed for use in
+[Hugo](http://hugo.spf13.com), a website engine which uses YAML, TOML or JSON
+for meta data.
+
+## Why use Cast?
+
+When working with dynamic data in Go you often need to cast or convert the data
+from one type into another. Cast goes beyond just using type assertion (though
+it uses that when possible) to provide a very straightforward and convenient
+library.
+
+If you are working with interfaces to handle things like dynamic content
+you’ll need an easy way to convert an interface into a given type. This
+is the library for you.
+
+If you are taking in data from YAML, TOML or JSON or other formats which lack
+full types, then Cast is the library for you.
+
+## Usage
+
+Cast provides a handful of To_____ methods. These methods will always return
+the desired type. **If input is provided that will not convert to that type, the
+0 or nil value for that type will be returned**.
+
+Cast also provides identical methods To_____E. These return the same result as
+the To_____ methods, plus an additional error which tells you if it successfully
+converted. Using these methods you can tell the difference between when the
+input matched the zero value or when the conversion failed and the zero value
+was returned.
+
+The following examples are merely a sample of what is available. Please review
+the code for a complete set.
+
+### Example ‘ToString’:
+
+ cast.ToString("mayonegg") // "mayonegg"
+ cast.ToString(8) // "8"
+ cast.ToString(8.31) // "8.31"
+ cast.ToString([]byte("one time")) // "one time"
+ cast.ToString(nil) // ""
+
+ var foo interface{} = "one more time"
+ cast.ToString(foo) // "one more time"
+
+
+### Example ‘ToInt’:
+
+ cast.ToInt(8) // 8
+ cast.ToInt(8.31) // 8
+ cast.ToInt("8") // 8
+ cast.ToInt(true) // 1
+ cast.ToInt(false) // 0
+
+ var eight interface{} = 8
+ cast.ToInt(eight) // 8
+ cast.ToInt(nil) // 0
+
