-# 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'.
