+# About terminfo [![GoDoc][1]][2]
+
+Package `terminfo` provides a pure-Go implementation of reading information
+from the terminfo database.
+
+`terminfo` is meant as a replacement for `ncurses` in simple Go programs.
+
+## Installing
+
+Install in the usual Go way:
+
+```sh
+$ go get -u github.com/xo/terminfo
+```
+
+## Using
+
+Please see the [GoDoc API listing][2] for more information on using `terminfo`.
+
+```go
+// _examples/simple/main.go
+package main
+
+import (
+	"bytes"
+	"fmt"
+	"log"
+	"os"
+	"os/signal"
+	"strings"
