+# QRCode Terminal
+
+[![Build Status](https://secure.travis-ci.org/mdp/qrterminal.png)](https://travis-ci.org/mdp/qrterminal)
+
+A golang library for generating QR codes in the terminal.
+
+Originally this was a port of the [NodeJS version](https://github.com/gtanner/qrcode-terminal). Recently it's been updated to allow for smaller code generation using ASCII 'half blocks'
+
+## Example
+Full size ASCII block QR Code:

+
+## Install
+
+`go get github.com/mdp/qrterminal`
+
+## Usage
+
+```go
+import (
+    "github.com/mdp/qrterminal"
+    "os"
+    )
+
+func main() {
+  // Generate a 'dense' qrcode with the 'Low' level error correction and write it to Stdout
+  qrterminal.Generate("https://github.com/mdp/qrterminal", qrterminal.L, os.Stdout)
+}
+```
+
+### More complicated
+
+Large Inverted barcode with medium redundancy and a 1 pixel border
+```go
+import (
+    "github.com/mdp/qrterminal"
+    "os"
+    )
+
+func main() {
+  config := qrterminal.Config{
+      Level: qrterminal.M,
+      Writer: os.Stdout,
+      BlackChar: qrterminal.WHITE,
+      WhiteChar: qrterminal.BLACK,
+      QuietZone: 1,
+  }
+  qrterminal.GenerateWithConfig("https://github.com/mdp/qrterminal", config)
+}
+```
+
+HalfBlock barcode with medium redundancy
+```go
+import (
+    "github.com/mdp/qrterminal"
+    "os"
+    )
+
+func main() {
+  config := qrterminal.Config{
+      HalfBlocks: true,
+      Level: qrterminal.M,
+      Writer: os.Stdout,
+  }
+  qrterminal.Generate("https://github.com/mdp/qrterminal", config)
+}
+```
