+# Prometheus Go client library
+
+[![Build Status](https://travis-ci.org/prometheus/client_golang.svg?branch=master)](https://travis-ci.org/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.
+
+## 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
+[best practices section](http://prometheus.io/docs/practices/naming/) of the
+Prometheus documentation 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)](http://gocover.io/github.com/prometheus/client_golang/api/prometheus) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/api/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/api/prometheus)
+
+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.
+
+## 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).

+# Overview
+This is the [Prometheus](http://www.prometheus.io) telemetric
+instrumentation client [Go](http://golang.org) client library.  It
+enable authors to define process-space metrics for their servers and
+expose them through a web service interface for extraction,
+aggregation, and a whole slew of other post processing techniques.
+
+# Installing
+    $ go get github.com/prometheus/client_golang/prometheus
+
+# Example
+```go
+package main
+
+import (
+	"net/http"
+
+	"github.com/prometheus/client_golang/prometheus"
+)
+
+var (
+	indexed = prometheus.NewCounter(prometheus.CounterOpts{
+		Namespace: "my_company",
+		Subsystem: "indexer",
+		Name:      "documents_indexed",
+		Help:      "The number of documents indexed.",
+	})
+	size = prometheus.NewGauge(prometheus.GaugeOpts{
+		Namespace: "my_company",
+		Subsystem: "storage",
+		Name:      "documents_total_size_bytes",
+		Help:      "The total size of all documents in the storage.",
+	})
+)
+
+func main() {
+	http.Handle("/metrics", prometheus.Handler())
+
+	indexed.Inc()
+	size.Set(5)
+
+	http.ListenAndServe(":8080", nil)
+}
+
+func init() {
+	prometheus.MustRegister(indexed)
+	prometheus.MustRegister(size)
+}
