+Go strcase
+==========
+
+The package `strcase` converts between different kinds of naming formats such as camel case 
+(`CamelCase`), snake case (`snake_case`) or kebab case (`kebab-case`).
+The package is designed to work only with strings consisting of standard ASCII letters. 
+Unicode is currently not supported.
+
+Versioning and stability
+------------------------
+
+Although the master branch is supposed to remain always backward compatible, the repository
+contains version tags in order to support vendoring tools.
+The tag names follow semantic versioning conventions and have the following format `v1.0.0`.
+This package supports Go modules introduced with version 1.11.
+
+Example
+-------
+
+```go
+import "github.com/stoewer/go-strcase"
+
+var snake = strcase.SnakeCase("CamelCase")
+```
