+# Gopher (RFC 1436) Web Proxy
+
+[![Build Status](https://travis-ci.org/prologic/gopherproxy.svg)](https://travis-ci.org/prologic/gopherproxy)
+
+This is a Gopher (RFC 1436) Web Proxy that acts as a gateway into Gopherspace
+by proxying standard Web HTTP requests to Gopher requests of the target server.
+
+gopherproxy is written in Go (#golang) using the
+[go-gopher](https://github.com/prologic/go-gopher) library.
+
+## Installation
+  
+  $ go install github.com/prologic/gopherproxy
+
+## Usage
+
+```#!bash
+$ gopherproxy
+```
+
+By default gopherproxy will proxy requests to a locally running Gopher server
+on gopher://localhost:70/ -- To change where to proxy to:
+
+```#!bash
+$ gopherproxy -host gopher.floodgap.com
+```
