 # YAML marshaling and unmarshaling support for Go
 
-[![Build Status](https://travis-ci.org/ghodss/yaml.svg)](https://travis-ci.org/ghodss/yaml)

+kubernetes-sigs/yaml is a permanent fork of [ghodss/yaml](https://github.com/ghodss/yaml).
 
 ## Introduction
 
 A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
 
-In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
