+# Gopher protocol library for Golang
+
+This is a standards compliant Gopher library for the Go programming language
+implementing the RFC 1436 specification. The library includes both client and
+server handling and examples of each.
+
+## Installation
+  
+  $ go get github.com/prologic/go-gopher
+
+## Usage
+
+```#!go
+import "github.com/prologic/go-gopher"
+```
+
+## Example
+
+### Client
+
+```#!go
+package main
+
+import (
+	"fmt"
+
+	"github.com/prologic/go-gopher"
+)
+
+func main() {
+	res, _ := gopher.Get("gopher://gopher.floodgap.com/")
+	bytes, _ = res.Dir.ToText()
+	fmt.Println(string(bytes))
+}
+```
+
+### Server
+
+```#!go
+package main
+
+import (
+	"log"
+
+	"github.com/prologic/go-gopher"
+)
+
+func hello(w gopher.ResponseWriter, r *gopher.Request) {
+	w.WriteInfo("Hello World!")
+}
+
+func main() {
+	gopher.HandleFunc("/hello", hello)
+	log.Fatal(gopher.ListenAndServe("localhost:70", nil))
+}
+```
