+# CamelCase [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/fatih/camelcase) [![Build Status](http://img.shields.io/travis/fatih/camelcase.svg?style=flat-square)](https://travis-ci.org/fatih/camelcase)
+
+CamelCase is a Golang (Go) package to split the words of a camelcase type
+string into a slice of words. It can be used to convert a camelcase word (lower
+or upper case) into any type of word.
+
+## Splitting rules:
+
+1. If string is not valid UTF-8, return it without splitting as
+   single item array.
+2. Assign all unicode characters into one of 4 sets: lower case
+   letters, upper case letters, numbers, and all other characters.
+3. Iterate through characters of string, introducing splits
+   between adjacent characters that belong to different sets.
+4. Iterate through array of split strings, and if a given string
+   is upper case:
+   * if subsequent string is lower case:
+     * move last character of upper case string to beginning of
+       lower case string
+
+## Install
+
+```bash
+go get github.com/fatih/camelcase
+```
+
+## Usage and examples
+
+```go
+splitted := camelcase.Split("GolangPackage")
+
+fmt.Println(splitted[0], splitted[1]) // prints: "Golang", "Package"
+```
+
+Both lower camel case and upper camel case are supported. For more info please
+check: [http://en.wikipedia.org/wiki/CamelCase](http://en.wikipedia.org/wiki/CamelCase)
+
+Below are some example cases:
+
+```
+"" =>                     []
+"lowercase" =>            ["lowercase"]
+"Class" =>                ["Class"]
+"MyClass" =>              ["My", "Class"]
+"MyC" =>                  ["My", "C"]
+"HTML" =>                 ["HTML"]
+"PDFLoader" =>            ["PDF", "Loader"]
+"AString" =>              ["A", "String"]
+"SimpleXMLParser" =>      ["Simple", "XML", "Parser"]
+"vimRPCPlugin" =>         ["vim", "RPC", "Plugin"]
+"GL11Version" =>          ["GL", "11", "Version"]
+"99Bottles" =>            ["99", "Bottles"]
+"May5" =>                 ["May", "5"]
+"BFG9000" =>              ["BFG", "9000"]
+"BöseÜberraschung" =>     ["Böse", "Überraschung"]
+"Two  spaces" =>          ["Two", "  ", "spaces"]
+"BadUTF8\xe2\xe2\xa1" =>  ["BadUTF8\xe2\xe2\xa1"]
