+Redigo
+======
+
+[![Build Status](https://travis-ci.org/garyburd/redigo.svg?branch=master)](https://travis-ci.org/garyburd/redigo)
+[![GoDoc](https://godoc.org/github.com/garyburd/redigo/redis?status.svg)](https://godoc.org/github.com/garyburd/redigo/redis)
+
+Redigo is a [Go](http://golang.org/) client for the [Redis](http://redis.io/) database.
+
+Features
+-------
+
+* A [Print-like](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Executing_Commands) API with support for all Redis commands.
+* [Pipelining](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Pipelining), including pipelined transactions.
+* [Publish/Subscribe](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Publish_and_Subscribe).
+* [Connection pooling](http://godoc.org/github.com/garyburd/redigo/redis#Pool).
+* [Script helper type](http://godoc.org/github.com/garyburd/redigo/redis#Script) with optimistic use of EVALSHA.
+* [Helper functions](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Reply_Helpers) for working with command replies.
+
