+
+Locales is a set of locales generated from the [Unicode CLDR Project](http://cldr.unicode.org/) which can be used independently or within
+an i18n package; these were built for use with, but not exclusive to, [Universal Translator](https://github.com/go-playground/universal-translator).
+
+Features
+--------
+- [x] Rules generated from the latest [CLDR](http://cldr.unicode.org/index/downloads) data, v31.0.1
+- [x] Contains Cardinal, Ordinal and Range Plural Rules
+- [x] Contains Month, Weekday and Timezone translations built in
+- [x] Contains Date & Time formatting functions
+- [x] Contains Number, Currency, Accounting and Percent formatting functions
+- [x] Supports the "Gregorian" calendar only ( my time isn't unlimited, had to draw the line somewhere )
+
+Full Tests
+--------------------
+I could sure use your help adding tests for every locale, it is a huge undertaking and I just don't have the free time to do it all at the moment;
+any help would be **greatly appreciated!!!!** please see [issue](https://github.com/go-playground/locales/issues/1) for details.
+
+Installation
+-----------
+
+Use go get 
+
+```shell
+go get github.com/go-playground/locales
+```  
+
+NOTES
+--------
+You'll notice most return types are []byte, this is because most of the time the results will be concatenated with a larger body
+of text and can avoid some allocations if already appending to a byte array, otherwise just cast as string.
+
+Usage
+-------
+```go
+package main
+
+import (
+	"fmt"
+	"time"
+
+	"github.com/go-playground/locales/currency"

+	fmt.Println(l.RangePluralRule(5, 0, 8, 0)) // 5-8
+}
+```
+
+NOTES:
+-------
+These rules were generated from the [Unicode CLDR Project](http://cldr.unicode.org/), if you encounter any issues
+I strongly encourage contributing to the CLDR project to get the locale information corrected and the next time 
+these locales are regenerated the fix will come with.
+
+I do however realize that time constraints are often important and so there are two options:
+
+1. Create your own locale, copy, paste and modify, and ensure it complies with the `Translator` interface.
+2. Add an exception in the locale generation code directly and once regenerated, fix will be in place.
+
+Please to not make fixes inside the locale files, they WILL get overwritten when the locales are regenerated.
