-# Prometheus Go client library
-
-[![Build Status](https://travis-ci.org/prometheus/client_golang.svg?branch=master)](https://travis-ci.org/prometheus/client_golang)
-[![Go Report Card](https://goreportcard.com/badge/github.com/prometheus/client_golang)](https://goreportcard.com/report/github.com/prometheus/client_golang)
-[![go-doc](https://godoc.org/github.com/prometheus/client_golang?status.svg)](https://godoc.org/github.com/prometheus/client_golang)
-
-This is the [Go](http://golang.org) client library for
-[Prometheus](http://prometheus.io). It has two separate parts, one for
-instrumenting application code, and one for creating clients that talk to the
-Prometheus HTTP API.
-
-__This library requires Go1.9 or later.__ The minimum required patch releases for older Go versions are Go1.9.7 and Go1.10.3.
-
-## Important note about releases and stability
-
-This repository generally follows [Semantic
-Versioning](https://semver.org/). However, the API client in
-prometheus/client_golang/api/… is still considered experimental. Breaking
-changes of the API client will _not_ trigger a new major release. The same is
-true for selected other new features explicitly marked as **EXPERIMENTAL** in
-CHANGELOG.md.
-
-Features that require breaking changes in the stable parts of the repository
-are being batched up and tracked in the [v2
-milestone](https://github.com/prometheus/client_golang/milestone/2). The v2
-development happens in a [separate
-branch](https://github.com/prometheus/client_golang/tree/dev-v2) for the time
-being. v2 releases off that branch will happen once sufficient stability is
-reached. In view of the widespread use of this repository, v1 and v2 will
-coexist for a while to enable a convenient transition.
-
-## Instrumenting applications
-
-[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/prometheus)](http://gocover.io/github.com/prometheus/client_golang/prometheus) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/prometheus)
-
-The
-[`prometheus` directory](https://github.com/prometheus/client_golang/tree/master/prometheus)
-contains the instrumentation library. See the
-[guide](https://prometheus.io/docs/guides/go-application/) on the Prometheus
-website to learn more about instrumenting applications.
-
-The
-[`examples` directory](https://github.com/prometheus/client_golang/tree/master/examples)
-contains simple examples of instrumented code.
-
-## Client for the Prometheus HTTP API
-
-[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/api/prometheus/v1)](http://gocover.io/github.com/prometheus/client_golang/api/prometheus/v1) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/api/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/api)
-
-The
-[`api/prometheus` directory](https://github.com/prometheus/client_golang/tree/master/api/prometheus)
-contains the client for the
-[Prometheus HTTP API](http://prometheus.io/docs/querying/api/). It allows you
-to write Go applications that query time series data from a Prometheus
-server. It is still in alpha stage.
-
-## Where is `model`, `extraction`, and `text`?
-
-The `model` packages has been moved to
-[`prometheus/common/model`](https://github.com/prometheus/common/tree/master/model).
-
-The `extraction` and `text` packages are now contained in
-[`prometheus/common/expfmt`](https://github.com/prometheus/common/tree/master/expfmt).
