+# logfmt
+
+Package logfmt implements utilities to marshal and unmarshal data in the [logfmt
+format](https://brandur.org/logfmt). It provides an API similar to
+[encoding/json](http://golang.org/pkg/encoding/json/) and
+[encoding/xml](http://golang.org/pkg/encoding/xml/).
+
+The logfmt format was first documented by Brandur Leach in [this
+article](https://brandur.org/logfmt). The format has not been formally
+standardized. The most authoritative public specification to date has been the
+documentation of a Go Language [package](http://godoc.org/github.com/kr/logfmt)
+written by Blake Mizerany and Keith Rarick.
+
+## Goals
+
+This project attempts to conform as closely as possible to the prior art, while
+also removing ambiguity where necessary to provide well behaved encoder and
+decoder implementations.
+
+## Non-goals
+
+This project does not attempt to formally standardize the logfmt format. In the
+event that logfmt is standardized this project would take conforming to the
+standard as a goal.
+
+## Versioning
+
+Package logfmt publishes releases via [semver](http://semver.org/) compatible Git tags prefixed with a single 'v'.
