+## 1.0.0
+
+Update to add a quiet zone border to the QR Code - #5 and fixed by [WindomZ](https://github.com/WindomZ) #8
+
+ - This can be configured with the `QuietZone int` option
+ - Defaults to 4 'pixels' wide to match the QR Code spec
+ - This alters the size of the barcode considerably and is therefore a breaking change, resulting in a bump to v1.0.0
+
+## 0.2.1
+
+Fix direction of the qr code #6 by (https://github.com/mattn)

+# 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:
+<img src="https://user-images.githubusercontent.com/2868/37992336-0ba06b56-31d1-11e8-9d32-5c6bb008dc74.png" alt="alt text" width="225" height="225">
+
+Smaller 'half blocks' in the terminal:

+
+## 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)
+}
+```
