+# inflect
+
+Inflections made easy for Go.
+
+[![Build Status](https://drone.io/github.com/chuckpreslar/inflect/status.png)](https://drone.io/github.com/chuckpreslar/inflect/latest)
+
+## Installation
+
+With Google's [Go](http://www.golang.org) installed on your machine:
+
+    $ go get -u github.com/chuckpreslar/inflect
+
+## Usage
+
+```go
+import (
+  "github.com/chuckpreslar/inflect"
+)
+
+func main() {
+  inflect.Pluralize("user") // users
+  inflect.Pluralize("knife") // knives
+  
+  inflect.Singularize("orders") // order
+  
+  inflect.UpperCamelCase("this_is_underscored_mixedCased-And-Hyphenated") // ThisIsUnderscoredMixedCasedAndHyphenated
+}
+```
+
+## Support
+
+* Pluralization and singularization of words with proper language rules.
+* Case transformation from and to upper camel casing, lower camel casing, underscoring, hyphenating, and constantization.
+
+## Documentation
