 ## Logger interface with implementations (Zap and Logrus)
 
+[![Build Status](https://api.travis-ci.com/arun0009/go-logger.svg?branch=master)](https://travis-ci.com/arun0009/go-logger)
+
 When we create go libraries in general we shouldn't be logging but at times we do have to log, debug what the 
 library is doing or trace the log. 
 
 We cannot implement a library with one log library and expect applications to use the same log library. We use two 
 of the popular log libraries [logrus](https://github.com/sirupsen/logrus) and [zap](https://github.com/uber-go/zap)
-and this `go-logger` library allows you to use either by using an interface. 
+and this `go-logger` library allows you to use either one by using an interface. 
+
+You can add your implementation if you want to add more log libraries (e.g. zerolog).

+## Installation
+
+go get -u github.com/arun0009/go-logger
+
+## Quick Start
+
+[logrus](https://github.com/sirupsen/logrus) example
+
+```go
+package main
+
+import (
+	"os"
+
+	"github.com/arun0009/go-logger/pkg/logger"
+	"github.com/sirupsen/logrus"
+)
+
+func main() {
+	logrusLog := logrus.New()
+	logrusLog.SetFormatter(&logrus.JSONFormatter{})
+	logrusLog.SetOutput(os.Stdout)
+	logrusLog.SetLevel(logrus.DebugLevel)
+	log, _ := logger.NewLogrusLogger(logrusLog)
+	log.WithFields(logger.Fields{
+		"foo": "bar",
+	}).Info("direct")
+}
+```
+
+[zap](https://github.com/uber-go/zap) example
+
+```go
+package main
+
+import (
+	"os"
+
+	"github.com/arun0009/go-logger/pkg/logger"
+	"go.uber.org/zap"
+	"go.uber.org/zap/zapcore"
+)
+
+func main() {
+	consoleEncoder := zapcore.NewJSONEncoder(zap.NewDevelopmentEncoderConfig())
+	core := zapcore.NewCore(consoleEncoder,
+		zapcore.Lock(zapcore.AddSync(os.Stderr)),
+		zapcore.DebugLevel)
+	zapLogger := zap.New(core)
+	log, _ := logger.NewZapLogger(zapLogger)
+	log.WithFields(logger.Fields{
+		"foo": "bar",
+	}).Info("direct")
+}
